A trait that is always expressed when this gene is present is called adominant trait
recessive trait
prime trait
strong trait

Answers

Answer:

i think it is a recessive trait, i hope this helped.

Explanation:

Final answer:

A trait that is always expressed when a gene is present is called a dominant trait. Dominant traits only require one copy of a gene to be expressed. An example is brown hair, which, when paired with a gene for blonde hair (a recessive trait), will express as brown hair because it is dominant.

Explanation:

In the field of genetics, a trait that is always expressed when a particular gene is present is called a dominant trait. This type of trait only requires one copy of a gene — from either parent — to be expressed. For example, if one parent gives a gene for brown hair (a dominant trait) and the other for blonde hair (a recessive trait), the offspring will have brown hair. Brown hair is dominant because it is expressed even when only one gene for it is present.

How does a bird's beak help you identify it's habitat?

Answers

The shape of the beak can tell you the function of that particular type of beak, and then the habitat in which the bird lives. For example, a bird with a long, slender beak most likely gets its food from hard to reach crevices in the ground or trees, and a bird with a short, thick beak most likely gets its food from either cracking items open or killing prey, because the shortness of the beak shows that it does not need to reach small places.
