Question

To determine if the inheritance pattern of the alleles for white and brown fur in mice is Mendelian or exhibits incomplete dominance, which type of crosses should be performed?

a. Cross white fur mice with white fur mice
b. Cross brown fur mice with brown fur mice
c. Cross white fur mice with brown fur mice
d. Cross mice with other fur colors

Answer 1

To determine the inheritance pattern of white and brown fur alleles in mice, the best approach is to cross white fur mice with brown fur mice.

Step-by-step explanation:

In order to determine if the inheritance pattern of the alleles for white and brown fur in mice is Mendelian or exhibits incomplete dominance, you should perform crosses between white fur mice and brown fur mice. This will help you to observe the phenotypic ratios of the offspring and determine if there is a dominant trait, recessive trait, or a blend of traits.

Performing a cross between white fur mice with white fur mice or brown fur mice with brown fur mice would only result in offspring with the same fur color, which wouldn't provide information about the inheritance pattern. Similarly, crossing mice with other fur colors wouldn't help in determining the specific inheritance pattern of white and brown fur alleles.
