WebMuch of Mendel's work with plants still forms the basis for modern plant genetics. Plants, like all known organisms, use DNA to pass on their traits. Animal genetics often focuses on parentage and lineage, but this can sometimes be difficult in plant genetics due to the fact that plants can, unlike most animals, be self-fertile. 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. 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).
