Answer:
D] XhY
Explanation:
This may be because since the parent individuals have the recessive alleles, the individuals might not fully gain all dominant alleles.
(shaded means that the individual has a dominant allele)
All the factors listed, that is population density, temperature, carrying capacity, rainfall and sunlight all effect the living conditions of organisms in a biome as well as the type of species that will be found there.
What are the options given? That you know of sisjhdisjsjdhdh
Hybrid = having one recessive and one dominant allele
This means that all of the flowers must have the genotype Bb.
Knowing this, let's make a Punnet Square.

As you can see, 3 of these are going to have the dominant trait and 1 is going to have the recessive trait. This corresponds to our 3:1 in our question, meaning that the black seeds must be dominant and the brown ones recessive.
Because they are dominant, the genotype for black seeds could be
BB <em /><em>or</em>
Bb.
