(03.06 MC)The law of segregation is derived from Mendel’s conclusions. Which of the follow describes the law of segregation? The two genes of a given trait separate, or segregate, during gamete production All the gametes produced by organisms with matching alleles for a given trait will have the same allele for that trait Egg and sperms will only receive one of the two genes for a given trait that are found in the organism’s other cells
