NATS 1675 Lecture Notes - Lecture 9: Robert Crippen, Pea, Homologous Chromosome
Document Summary
Nats 1675 lecture #9 genetics part 2. It is a population of organisms that retain their individuality in nature because they are reproductively isolated from other species from them. Reproductive isolation: both include behavior & genetics ; both also include distance and barrier. Behavioural breakdown in reproductive isolation: a male chicken and female ferret have an interest in one another. An organism produced by 2 different species or genotypes. There are cases where different and related species mate and they can reproduce offspring. One example most people are familiar with is the crossover of the female horse and a male donkey so their offspring is a mule. Another example is a male horse and female donkey so their offspring is a hinny. You see [above] how just changing the parents , it can make a difference forming a baby. Hybrids are usually incapable of reproduction themselves their chromosomes are similar enough that they are unable to reproduce.
