BIOLOGY 151 Lecture Notes - Lecture 29: Mendelian Inheritance, Zygosity, Meiosis
Document Summary
Heterozygous +heterozygous- big t"s separate into one gene, litle t"s go into another. Two factor cross- follow inheritance of 2 diferent traits. Possible paterns- plant that"s tall with yellow and round and a plant that"s green and wrinkled. 1 possibility- one with yellow and round or green and wrinkled. All combinaions are possible. trait on the same chromosome- traits are linked and stay together. They"re not always on the same chromosome though. Independent assortment- alleles of diferent genes assort independently during gamete formaion during meiosis if they are on diferent chromosomes. Mendelian geneics: inheritance patern of genes that segregate and assort independently. Simple mendelian inheritance: the manner by which genes and traits are passed from parents to their children. The modes of mendelian inheritance are often dominant, recessive, x-linked dominant, and x-linked recessive. Wild-type allele: prevalent allele in a populaion, encodes a protein made in the proper amount and funcions normally. Defecive in its ability to express a funcional protein.
