Answer:
Okay let me break this down, so you have a pure red and pure white feathered chicken meaning that the chickens have homologous alleles. Overtime, as you breed the two you may get multicolored chickens but they can carry the recessive white feathers alleles (FWFW) meaning that they can still produce all white chickens and they can continuously do that over generations. Selective breeding may be negative because you may not get the desired result, you could breed for the wrong traits, other characteristics are lost and the resulting population is very similar. Less genetic variation can cause the chickens to not be resistant to problems like diseases and could fall ill.
Explanation:
If one parent has been affected by sickle cell anemia, while the other parent does not and is homozygous, the chances that a child will have this disorder is 0%. Thus, the correct option is C.
<h3>What is Sickle Cell anemia?</h3>
Sickle Cell anemia may be defined as a genetic disorder that is caused by a recessive allele. It is an inherited disease in which the red blood cells have an irregular crescent shape, obstruct small blood vessels, etc.
This disease is inherited when both genes of each parent are supposed to be defective or carriers. While in this case, only parents are affected by the disorder while the other is homozygous for the normal allele.
In this condition, all the offspring produced by both parents remain as carriers but not affected ones.
Thus, the correct option is C.

Protein is assembled inside cells by an organelle called a ribosome. Ribosomes are found in every major cell type and are the site of protein synthesis.
