Web10 aug. 2024 · Heterozygous means that an organism has two different alleles of a gene. For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). WebScience Biology In garden peas, long stems are dominant to short stems, and yellow seeds are dominant to green seeds. 100 long/yellow pea plants, all of which had one short/green parent, are interbred (bred to each other). 1600 progeny result.

Weban enzyme coded for by a gene. Short plants have a mutation in the gene that codes for GA 3-beta-hydroxylase, the enzyme for the last step of the pathway (Figure 5; Lester et al., 1997). Short is reces-sive: heterozygous plants, despite making only half as much of this enzyme, produce enough gib-berellin that they are over 6 feet tall.
