PPT-Chromosome inversions in human populations

Marta Ruiz Fernández Master in Advanced Genetics 17 December 2014 INTRODUCTION Inversions occur when a chromosome breaks at two points and the segment between the breakpoints is reinserted in the reverse orientation.

Introduction This leaflet is written for individuals who have a chromosome inversion and for members of their family. It is intended to explain what a chromosome inversion is, what it means for the 1.Inverted segment do not 2.Crossing over within the 3.The crossover products 4.Paracentric inversions do not The products of single crossing over will not function and the only crossover products LECTURE 32 A. Pairing of inversion genotypes: : a) No crossing over:Only parental types (two chromosomes and two in chromosomes) are 2 Pericentric inversions : a) No crossing over:The result is the unsortedness. is the number of inversions. Review of inversions. Distribution of inversions for randomly generated lists. Counting inversions:. Straight-forward algorithm is has a . Q. (. n. 2. ). run time. Important. Notes. For revision only. Objectives: . Describe the number, structure, and classification of human chromosomes . Explain what a Karyotype is and how it is obtained. . Describe chromosomal banding and explain its use. .
