| Advantages of Sexual Reproduction |
|
Definition
| 1.)Introduces Genetic variability through: A.)crossing over in prophase I of Meiosis. B.) Independent assortment in meiosis. C.) Random fertilization................2.) Allows adaptation to variable enviornments..............3.)Way to repair certain kinds of chromosome damage; synaptonemal complex-repair as homologous chromosomes align............4.) Two parents to care for young |
