Suppose you have monohybrid flowers in your garden and find that they produce black seeds to brown seeds in the ratio of 3:1. If
Dvinal [7]
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.

\begin{tabular}{ l c } & B \ \ \ \ b\\ B & \boxed{BB}\boxed{Bb} \\ b & \boxed{Bb\ }\boxed{\ bb} \\ \end{tabular}

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.

VARVARA [1.3K]
The answer is D, white blood cells.

The main function of white blood cells is to defense the body from bacteria or other pathogens. There's 2 main kinds of white blood cells, lymphocytes and phagocytes. Lymphocytes mainly produce antibodies that can kill bacteria or any pathogens, and phagocytes can ingest the pathogens directly.

Therefore, since the white blood cells can protect our body, they're part of our immune system.
