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.

Most animals are producers, meaning they are able to create their own food from inorganic sources.
skad [1K]
<span>This is false since plants are mostly producers and animals are mostly consumers. There is however a group of animals that are autotrophs and create their own food, but they are vastly outnumbered by consumers. The ones that produce their own are mostly within the family of funghi or similar things that border on whether they're animals or plants.</span>
