Each body cell contains the same number and kinds of chromosomes for that organism. The chromosomes contain the same number and kinds of genes for that individual.
4.b 5.c 6.c is the right answer
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
The second one probably because of the law of conservation of mass where mass is not created or destroyed, so the mass has to be the same.
