Learn about life and living organisms in our biology simulations for Majors. Humans have 22 pairs of autosomes. Ploidy level changes from diploid to haploid in meiosis I, and remains haploid in meiosis II. Mendel found that paired pea traits were either dominant or recessive.When pure-bred parent plants were cross-bred, dominant traits were always seen in the progeny, whereas recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate. Its also possible to use Labster without an LMS.
