Question

A scientist crossed two species of mouse and found that, among the hybrid offspring, males were sterile but females were viable and fertile. This seems to be an example of

A) Wasted time and effort

B) Haldane's rule

C) Darwin's corollary

D) Murphy's law

E) Mendel's law of sex-linked inheritance

Answer 1

This is an example of Haldane's rule. Haldane's rule states that when there is hybrid infertility or inviability in the offspring of two different species, it is more likely to occur in the heterogametic sex than in the homogametic sex.

Step-by-step explanation:

This is an example of Haldane's rule. Haldane's rule states that when there is hybrid infertility or inviability in the offspring of two different species, it is more likely to occur in the heterogametic sex (the sex with dissimilar sex chromosomes) than in the homogametic sex (the sex with similar sex chromosomes). In this case, the hybrid offspring of the scientist's experiment are male and female mice. The males are sterile, which is an example of hybrid infertility, while the females are viable and fertile.
