A man who is a dwarf due to achondroplasia and has normal vision marries a color-blind woman of normal height. The man's father was 6 feet tall, and both the woman's parents were of average height. Achondroplasia is autosomal dominant, and red-green color blindness is X-linked recessive. How many of the couple's daughters might be expected to be color-blind dwarfs

None of their daughters.

Explanation: For the purposes of this exercise, we shall take it as a given that red-green color blindness has an X-linked recessive inheritance pattern. Since the man (who possesses only one X chromosome) does not have color blindness, we can assume that he is not a carrier of a pathogenic allele for this trait. His female partner, in contrast, does have the disease despite being in possession of two X chromosomes and we can therefore assume that each of those X chromosomes contains a pathogenic allele.

Each of the couple's potential daughters will inherit two X chromosomes. The one inherited from the father's side will contain a normal allele (barring the potential for de novo mutations), while the one inherited from their mother will contain a pathological allele. Since it takes two affected alleles for the disease to become manifest, those daughters will be merely asymptomatic carriers.

In conclusion: none of the daughters (affected by dwarfism, or otherwise) will be colorblind.

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.
