You crossed two heart shaped Shepherd’s purse which is heterozygous at one locus and homozygous recessive at other gene locus, what would be the ratio of heart shaped and narrow in F1?

You crossed two heart shaped Shepherd’s purse which is heterozygous at one locus and homozygous recessive at other gene locus, what would be the ratio of heart shaped and narrow in F1? Correct Answer All heart

As the parent is homozygous recessive at one locus and heterozygous at the other, the combinations that are yield would give 3:1 ratio of heart to narrow.
