Meiosis and Genetics: • B = no baldness, b = bald. Segregation actually happens here during anaphase of meiosis I •What are the diploid and haploid numbers for this imaginary organism? Diploid (2n) = 2 Haploid (n) = 1 •Explain how this diagram of meiosis could relate to Mendel’s idea that two “factors” must control a trait. An individual has two genes or as Mendel called them “factors” for a trait. Each gene was inherited from a parent (in this case B and b). •How does this diagram relate to the law of segregation? When this individual makes gametes the alleles B and b must segregate into separate gametes. Genes are assorted randomly to gametes – assortment depends on how homologous pairs align in metaphase of meiosis I, alignment of maternal and paternal chromosomes is random
