What is a gene? a section of a protein that codes for DNA
the alternate version of a trait
the visible trait in the F1 generation
a section of DNA that codes for a specific trait

A gene is an order of nucleotides in DNA or RNA that encodes the structure of a gene product, either RNA or protein. During gene expression, the DNA is copied into RNA. The RNA can be directly functional or be the standard template for a protein that performs a function.

D. a section of DNA that codes for a specific trait

Explanation:

got it right in edg 2021

see pic

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

if either parent mouse passes a dominant allele, the offspring will have black fur.

if the parental mice has two different fur color (i.e white and black) , the color of the offspring's fur would be either black, white, or the combination of both (grey)

hope this : )

true is the final answer!
