Awesome StudentQuestion • Biological Science

When closely related individuals mate with each other, or inbreed, the offspring are often not as fit as the offspring of two unrelated individuals. Why?

Answer

Inbreeding causes normally silent alleles to be expressed

#BIO-6202

Awesome StudentQuestion • Biological Science

In most stable freshwater environments, populations of Daphnia are almost entirely female and reproduce asexually. However, males are observed in low oxygen environments or when food is scarce. Based on these observations, a researcher suggests that male Daphnia develop in response to unfavorable environmental conditions. This is an example of a:
