Answer:
Crossing two chickens heterozygous for the trait feather color, when brown feathers are dominant over red feathers, will produce offspring with brown and red feathers in a brown:red phenotypic ratio of 3:1.
Explanation:
Knowing that in chickens brown feathers are the expression of the dominant allele (B) and the recessive allele is red (b), crossing two heterozygous individuals (Bb) will result in offspring that are likely to have brown or red feathers.
The cross can be represented by a Punnett Square:
<u>Bb X Bb cross
</u>
alleles B b
B BB Bb
b Bb bb
Where the result is:
<u>Genotypes</u>:
<u>Phenotypes</u>:
- Brown feathers, 75%
- Red feathers, 25%.
In this case, the probability of having brown or red feathers is 3:1.
Answer:
The codon AUG, commonly known as the start codon, specifies the amino acid methionine. As a result, during protein synthesis, methionine is the first amino acid to dock in the ribosome.

Pride can be a positive trait as it helps an individual gain confidence in their work and skills, making them more successful and happier. However, pride can be negative as it may cause one to believe they are entitled to their success, and also may cause them to treat others inferiorly. Hope this helps! :)
<span>They are misleading, because dominant alleles do not dominate or prevent recessive alleles from doing a job. Also, one allele can be considered dominant in one regard and recessive in another. It just depends on what you are trying to do with it.</span>
