Two trait crosses
WebOct 4, 2024 · The test cross is an experiment first employed by Gregor Mendel, in his studies of the genetics of traits in pea plants. Mendel’s theory, which holds true today, was that each organism carried two copies of each trait. One was dominant trait, while one could be considered recessive. The dominant trait, if present, would determine the outward ... WebThe law of segregation states that the two alleles of a single trait will separate randomly, meaning that there is a 50% either allele will end up in either gamete. This has to do with 1 gene. The law of independent assortment states that the allele of one gene separates independently of an allele of another gene.
