Suppose you have monohybrid flowers in your garden and find that they produce black seeds to brown seeds in the
ratio of 31. If the allele are designated (B & b) respectively, what are the probable genotypes of the black seeds
produced by your plants?

Answer :

Answer:

The black seeds will be heterozygous Bb

Explanation:

 To produce the outcomes of a cross with 3:1, the following cross can be made:

       B             b

B   BB           Bb

b    Bb          bb

The results from this punnet square show that a 3:1 ratio will be achieved when two heterozygous black seed plants are crossed. The plants will have the chances of producing 25% homozygous black seeded plants, 50% chance of producing heterozygous black seed plants and 25% chance to produce brown seeds.
