Answer:
<h2>B) BB</h2>
Explanation:
The gene for feather color is controlled by codominance ( codominance, when both the alleles express their effect, the phenotype is the combination of both alleles, it is the intermediate of both phenotypes).
black feathers is B
erminette feathers WB
white feathers is W
Then the genotype for chickens with black feathers is BB.
also the Bb may be black this is heterozygous condition.
Carbon dioxide is the answer to this qestion
The red-green color blindness is X-linked recessive traits. It is known that male has one X chromosome and one Y chromosome. So, if he inherits recessive allele from his mother, he will be colorblind.
It is more complicated for females because they have two X chromosomes. Similarly to Mendelian monohybrid cross, a female which is recessive homozygous will be colorblind (X^cbX^cb). But a heterozygous female (<span>X^CBX^cb) will be rarely color because she has one dominant allele.</span>
