In pea plants the purple allele at the flower color locus is

In pea plants, the purple allele at the flower color locus is dominant to the white allele. You cross two heterozygous plants and see the following results: 162 purple: 43 white. Based on your knowledge of monohybrid crosses, what ratio of purple to white flowers would you expect from this cross?

O 1 purple: 1 white O 3.76 purple: 1 white O all purple O 3 purple :1 white

Solution

In a cross between heterzygous we should get 3:1 in ratio 3 purple n 1 white. so
