LIFE 120 Lecture Notes - Lecture 14: Meiosis, Non-Coding Rna, Haemophilia
Document Summary
Mendel"s first law is also known as the law of segregation. "the alleles of a given locus segregate into separate gametes. : alleles sort independently because the gene is located on a specific chromosome. The law of independent assortment states that each pair of alleles segregates independently of each other pair of alleles during gamete formation. 12. 1 mendelian inheritance has its physical basis in the behavior of chromosomes. Mitosis and meiosis were first described in the late 1800s. The chromosome theory of inheritance states: mendelian genes have specific loci (positions) on chromosomes o. The behavior of chromosomes during meiosis can account for mendel"s laws of segregation and independent assortment. Thomas hunt morgan and his students began studying the genetics of the fruit fly, drosophila melanogaster, in 1907. Several characteristics make fruit flies a convenient organism for genetic studies o. They produce many offspring: a generation can be bred every 2 weeks. They have only 4 pairs of chromosomes o.
