Question

A Plant with heterozygous alleles for height is:

Options
  • A

    Dihybrid

  • B

    Dual hybrid

  • C

    Heterotype

  • D

    Hybrid

Explanation

A hybrid is an organism that has parents of different breeds, varieties, or species. In this context, a plant with heterozygous alleles for height is a hybrid because it has inherited different alleles for height from its two parent plants, which could be of different varieties or breeds.

Dihybrid refers to an organism that is heterozygous for two different traits governed by different genes, not necessarily related to height

There is no specific biological term "dual hybrid." It seems to be a combination of "dihybrid" and "hybrid," but it is not a recognized term in genetics.

Heterotype generally refers to a cell or organism that has different chromosome sets, such as in hybridization, but it is not commonly used to describe the genetic state of an individual plant with heterozygous alleles for height.
