Varieties of plants in which self-fertilization produces offspring that are identical to the parents are referred to as

C) monohybrid crosses.
D) true-breeding.

Question

Quizplus · Accepted Answer

True-breeding refers to a type of plant in which self-fertilization will produce offspring that are identical to the parent. This is because the true-breeding plant has homozygous alleles for a particular trait, meaning that both alleles for a given trait are the same. Therefore, any offspring produced through self-fertilization will inherit the same homozygous alleles and display the same traits as the parent plant. This is in contrast to hybrid plants, which come from the cross-fertilization of different true-breeding plants and may display a combination of traits from each parent. The F2 generation and monohybrid crosses refer to specific types of genetic experiments or breeding patterns and are not necessarily related to true-breeding plants.
