Mutation that involves a single nucleotide is called?
Point Mutation is the mutation that involves a single or few nucleotide. This type of mutation replaces a single nucleotide to another.
Is polydactyly common in men or women?
Polydactyly is more common in men, because it is a genetic disorder. Because females have 2 X chromosomes, a recessive trait passed down on one will be covered by the dominant trait on their other X chromosome for no polydactyly. Males though, have an X and Y chromosome which means that that the Y chromosome, carrying no trait for polydactyly, will not affect an X chromosome with the allele for polydactyly. Hence, polydactyly is found in men more than women.
