Selective breeding

Mating organisms with desirable traits for favourable offspring

Selective breeding offspring fertility

Fertile (parents are same species)

Artificial insemination (AI)

Sperm collected from male & inserted into female without mating

AI sperm storage method

Frozen in liquid nitrogen

Main disadvantage of AI

Reduces genetic diversity in populations

In vitro fertilisation (IVF)

Egg fertilised by sperm outside mother's body

MOET (Multiple Ovulation Embryo Transfer)

Stimulates female to produce multiple eggs in one cycle

IVF effect on infertility genes

Allows infertility genes to be inherited by offspring

Artificial pollination

Manual transfer of pollen from anthers to stigma

Artificial pollination genetic diversity effect

Increases genetic variability through hybridisation
