WebMonohybrid Crosses. A monohybrid cross is one in which both parents are heterozygous (or a hybrid) for a single (mono) trait. The trait might be petal color in pea plants. When conducting crosses, the first generation is called P (or P 0 ), the second generation is F 1 (F is for filial), and the next generation is F 2. Much 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 … Meer weergeven Plant genetics is the study of genes, genetic variation, and heredity specifically in plants.
