there are genes that govern the eye color of mice, too. suppose that a true - breeding mouse with red eyes is crossed with a true - breeding mouse with black eyes. all of the offspring mice have black eyes. what can you conclude?
Answer
Brief Explanations:
In genetics, when two true - breeding individuals with different phenotypes are crossed and all offspring show one phenotype, the allele for that phenotype is dominant. Here, since all offspring of red - eyed and black - eyed true - breeding mice have black eyes, the allele for black eyes is dominant over the allele for red eyes.
Answer:
The allele for black eyes is dominant over the allele for red eyes.
