Polydactyly is an inherited human trait in which the affected individual has extra fingers or toes. this defect results from the
dominance of the defective gene (p) over the normal allele (p). a. if a man with polydactyly (assume that he is heterozygous) marries a normal woman, what are the possible genotypes of their children
In order for a recessive gene to be in a persons phenotype, they would have to be homozygous recessive so it would be impossible for the man to have polydactyl if he’s heterozygous.
However, assuming that he is homo recessive with polydactyl and he marries a homozygous dominant woman, the offsprings would have a 100% chance of not having polydactyl
If he marries a heterozygous woman, they offsprings would have a 50/50 change of having/not having polydactyl
Autorophs are living organisms that make their food through photosynthesis while heterotrophs are living organisms that can not make their own food, so they must eat it.
