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?

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.          

the most common type of reef is the fringing reef. this type of reef grows seaward directly from the shore. they form borders along the shoreline and surrounding islands.
