LIFE 102 Lecture Notes - Lecture 15: Mendelian Inheritance, Trisomy, Natural Selection
Document Summary
Chapter 15- chromosomal inheritance (cont. from notes) iclicker: males are functionally haploid for x linked genes and get their gene from their mother. All of the cells in the half black half orange cat effected each other. The half of the face that is orange deactivated the black allele and the half that is black deactivated the orange allele. Genetic linkage- violation of the law of independent assortment. Use recombination frequency to map the relative location of genes to each other on chromosomes. Deletion in a functional region can be detrimental: duplication. Natural selection can act on them. (cid:862)i(cid:373)porta(cid:374)t i(cid:374) evolutio(cid:374)(cid:863) All genes are present but not in normal position. Not necessarily good or bad: translocation. Changes in gene expression but genes are all there iclicker: a male parent with colorblindness can have a child with colorblindness only if the mother has the recessive allele. Rosalind franklin discovered the width of the dna molecule.
