Answer: B (Color blindness)
Explanation:
Typical red-green color blindness in human patients is caused by mutations on genes located in the X chromosome. These mutations act in a recessive manner. Since females have two X chromosomes, the presence of a mutation in a single one of them does not normally result in color blindness. Males, in contrast, have a single X chromosome and therefore the presence of a mutation is likely to cause the disease.
About the other options: Down‘s syndrome is a numerical chromosomal anomaly, not related to sex. Human blood type is a codominant trait. Finally, tail length in dogs is a polygenic trait not amenable to classic Mendelian analysis.
Answer:
d. platelets
Explanation:
Platelets often referred to as thrombocytes, are membrane-bounded cell fragments that are obtained from the dissociation of bigger precursor cells referred to as megakaryocytes, that are produced from stem cells in the bone marrow.
Platelets are necessary for the blood clotting activities, making it very important for wound healing.
