7. Mendel’s Laws Heterozygous parents are equally likely to donate either of their alleles to offspring - allele donated to gametes is random Mendel’s Law of Segregation Recall that in meiosis - a parent contributes only one of its two alleles for a trait Each embryo has exactly the same chance of receiving a particular allele from each parent Example: equal chance of an X or Y allele from male – sex ratio of offspring is 50:50 For multiple alleles – the segregate independently ( Law of Independent Assortment )
