Considering that we are all made up of the same 4 nucleotides in our DNA, the same 4 nucleotides in our RNA, and the same 20 ami
Sladkaya [172]
The order that the nucleotides are arranged in form different "codes" to create traits. RNA in humans is used for transporting, and making the amino acid proteins. The order of amino acid proteins also changes the polypeptide formed, and changes more traits, and characteristics. Basically, it's like reading a book. Each book is made up of the same 26 letters, but their all arranged in different orders. You can find the some of the same words in another book, but no two books are exactly alike.

kondor19780726 [428]

Answer:

See the answer below

Explanation:

<em>Genotype is the genetic composition of organisms and a gene is made up of two alleles.</em>

a) Since the allele for black is B, <u>the genotype for black chickens would be BB. </u>

b) Since the allele for white is W, <u>the genotype for white chickens would be WW.</u>

c) Since erminette color is heterozygous,<u> the genotype would be BW.</u>

d) Two erminette were crossed:

         BW    x    BW

      BB BW BW WW

i. <em>Probability of having black chick (BB) </em>= 1/4

ii. <em>Probability of having a white chick (WW)</em> = 1/4

iii. <em>Probability of having erminette chicken (BW)</em> = 1/2
