Question

Quizplus · Accepted Answer

Inbred lines are created by repeated self-fertilization or interbreeding of closely related individuals for several generations, resulting in homozygosity for most or all genes. This can be done in both plants and animals, and while some human populations may exhibit higher levels of inbreeding, inbred lines specifically refer to experimental populations bred for genetic homogeneity. Therefore, the best choice is D, homozygous for all genes.
