Document Summary

Types of variation: 3 types of variability, 1. Mutations = new genetic variation: heritable changes in dna. 3. 5 ml of ejaculation @ 300 m/ml= approx. 1 gamete mutated in 100 000 to 1 m. 20 000 protein-coding genes in your sperm counts for only 1. 5 % human genome odds 1:50 to 1:5 sperm carry mutation: major source of variation!!! Can be neutral, deleterious, lethal, advantageous: 2.
