Eggs
They consist of an outer shell, membrane, and internal contents including the yolk and albumen.
Eggs provide essential nutrients and serve as a source of nourishment for the developing embryo.
Studying the properties and characteristics of eggs is crucial for understanding reproductive biology, nutrition, and developmental processes across a variety of species.

Healthy plant food groups included whole grains, fruits, vegetables, nuts, legumes, vegetable oils, and tea/coffee, whereas less healthy plant food groups included fruit juices, sugar-sweetened beverages, refined grains, potatoes, and sweets/desserts. Animal food groups included animal fats, dairy, eggs, fish/seafood, meat (poultry and red meat), and miscellaneous animal-based foods.
Heterozygous F2 fish were randomly incrossed and upon egg collection F2 adults were fin clipped and kept as isolated breeding pairs. For each family we aimed to phenotype 12 pairs, over 3 weeks of breeding. Each clutch of eggs, which was labelled with the breeding pair ID, was sorted into three 10cm petri dishes of ~50 embryos each. Embryos were incubated at 28.5°C. Previous mutagenesis screens were used as a reference for the phenotyping 27 (link),28 (link). Those phenotypes studied were: day 1 – early patterning defects, early arrest, notochord, eye development, somites, patterning and cell death in the brain; day 2 – cardiac defects, circulation of the blood, pigment (melanocytes), eye and brain development; day 3 – cardiac defects, circulation of the blood, pigment (melanocytes), movement and hatching; day 4 – cardiac defects, movement, pigment (melanocytes) and muscle defects; day 5 – behaviour (hearing, balance, response to touch), swim bladder, pigment (melanocytes, xanthophores and iridophores), distribution of pigment, jaw, skull, axis length, body shape, notochord degeneration, digestive organs (intestinal folds, liver and pancreas), left-right patterning. In the first round of the phenotyping, all phenotypic embryos were discarded. At 5 dpf, >48 phenotypically wild-type embryos were harvested. Embryos were fixed in 100% methanol and stored at −20°C until genotyping was initiated. In the second round, F2s that were heterozygous for a suspected causal mutation were re-crossed. All phenotypes observed in those clutches of embryos were counted, documented and photographed. Phenotypic embryos were fixed in 100% methanol and at 5 dpf 48 phenotypically wild-type embryos were also collected. The first round genotyping results were assessed using a Chi-squared test with a p-value cut off of <0.05. If the number of homozygous embryos was above the cut-off (i.e. in the expected 25% ratio), the allele was deemed to not cause a phenotype within the first 5 dpf. If the number of homozygous embryos was below the cut-off, the allele was carried forward into the second round of phenotyping. In the second round, we aimed to genotype 48 embryos for each phenotype, ideally from multiple clutches. An allele was documented as causing a phenotype if the phenotypic embryos were homozygous for the allele. We allowed up to 10% of embryos for a given phenotype to not be homozygous, to account for errors in egg collection. Such alleles were outcrossed for further genotyping with F4 embryos at a later date. Where possible, alleles were also submitted to complementation tests.

Example 20
Coffee cake was made from cake batter comprising the following ingredients:
The coffee cake was made in a glass cake pan into which the cake batter was placed and baked at ordinary temperature and time in an oven according to the recipe. The coffee cake was comparable or superior in quality and taste compared to coffee cake made using traditional all-purpose or cake flour and had superior nutritional profile. The coffee cake was lighter, fluffier, and more moist compared to conventional coffee cake made using all-purpose flour instead of the composite wheat-MCT flour.
Example 8
Lung tissues from the 7 dogs were analyzed by quantitative real-time RT-PCR assays that detect the M gene of influenza type A and the H3 gene of canine H3N8 influenza A virus. The lungs from all 7 dogs were positive for both the influenza A M gene and the canine influenza H3 gene (Table 8). After 3 passages in MDCK cells, influenza A subtype H3N8 virus was isolated from the lungs of a shelter dog that died after 3 days of pneumonia. This virus was named A/canine/Jacksonville/05 (H3N8) (canine/Jax/05). After 2 passages in embryonated chicken eggs, influenza A subtype H3N8 virus was recovered from the lungs of the pet dog that also died after 3 days of pneumonia. This virus was named A/canine/Miami//05 (H3N8) (canine/Miami/05).
Example 5
This example describes the superior protection of plant comprising event MON 87411 from corn rootworm damage when compared to current commercial products (MON 88017 and DAS-59122-7) and negative control plants. Efficacy field trials were conducted comparing 135 plants each of event MON 87411, MON 88017, DAS-59122-7, and negative controls. Root damage ratings (RDR) were collected, and the percentage plants with an RDR less than the economic injury level (0.25 RDR) is shown in Table 8.
Table 8 shows that only about 4% of plants containing event MON 87411 exhibited RDRs greater than the economic threshold of 0.25 RDR. In contrast, 22% of the commercially available plants containing MON 88017 exhibited RDRs greater than the economic threshold of 0.25 RDR. And, 20% of the commercially available plants containing DAS-59122-7 exhibited RDRs greater than the economic threshold of 0.25 RDR. And, 96% of the negative control plants exhibited RDRs greater than the economic threshold of 0.25 RDR. The conclusion from these data is that event MON 87411 is clearly superior at providing protection from corn rootworm damage as compared to commercial products MON 88071 and DAS-59122-7, and a negative control.
Trial included 135 plants for each event tested.
Efficacy green house trials were conducted to test the performance of event MON 87411 with extreme infestation pressure of corn root worm. In this trial the following event were evaluated: event MON 87411, an event from transformation with DNA vector #890 expressing only the dsRNA; MON 88017; DAS-59122-7; and negative control. For these high-pressure efficacy trials, the corn plants under evaluation were grown in pots in a green house. Extreme infestation pressure was achieved by sequential infestation of each potted plant with approximately 2,000 WCR eggs per pot at their V2 growth stage, and, at 4 additional times occurring at 1 to 1½ week intervals with approximately 1,000 WCR eggs per pot per infestation for a total of approximately 6,000 WCR eggs added to each pot. Plant roots were removed, washed, and rated for RDR at their VT growth stage. The roots from all thirteen (N=13) negative control plants exhibited maximum root damage, or an absolute RDR of 3 RDR. These results illustrate that event MON 87411 is more superior to other corn events available for controlling corn rootworm (Table 9).
One measure of efficacy of corn rootworm transgenic events is by a determining the emergence of adult beetles from the potted soil of plants cultivated in a green house. To determine adult corn rootworm beetle emergence from the soil of event MON 87411 plants grown in pots, 10 to 15 plants were germinated in pots containing soil infested with WCR eggs, similar to that described above. Throughout the growth period, each corn plant was covered with mesh bag to contain any emerging adult beetles.
Counts of above ground adult beetles were made at 6, 12, and 18 weeks after plant emergence, and at the end of the trial the roots were evaluated for RDR. Plants containing event MON 87411 were compared to negative control plants, and other corn rootworm protective transgenic events. The results were that significantly fewer beetles were observed to emerge from soils in which event MON 87411 plants were potted compared to the other corn rootworm protective transgenic events, illustrating the superior properties of event MON 87411 to protect against corn rootworm damage.

Banana nut bread was made from cake batter comprising the following ingredients:
The banana nut bread was made in a greased metal bread pan into which the cake batter was placed and baked at ordinary temperature and time in an oven according to the recipe. The banana nut bread was comparable or superior in quality and taste compared to banana nut bread made using traditional all-purpose or cake flour and had superior nutritional profile. The banana nut bread was lighter, fluffier and more moist compared to conventional banana nut bread made using all-purpose flour instead of the composite wheat-MCT flour.
