Alternation of generations also known as metagenesis or heterogenesis is the predominant type of life cycle in plants and algaeIt consists of a multicellular haploid sexual phase the gametophyte which has a single set of chromosomes alternating with a multicellular diploid asexual phase the sporophyte which has two sets of chromosomes. Reproductive isolating mechanisms can prevent different species from interbreeding.

You can see in the first generation F1 that all offspring produce round seeds even though they both the round and wrinkly alleles.
. The reproductive systems allow human reproduction. Can Different Species Hybridize. Reproductive isolation is maintained due to lack of hybrid survival.
Hybrids have lower fitness than either parent species. If the F1 generation self-fertilizes pea plants like most plants produce both male and female gametes then you now see some offspring that produce rounds seeds and some that produce wrinkly seeds. In 1866 he published his work Experiments in Plant Hybridization 1 in the proceedings of the Natural History Society of Brünn.

Mendels work went virtually unnoticed by the scientific community which incorrectly believed that the process of inheritance involved a blending of parental traits that produced an intermediate physical appearance in offspring. But when interspecies mating does occur there are several possible outcomes.
