What are the positive and negative effects of inbreeding?

Inbreeding results in homozygosity, which can increase the chances of offspring being affected by deleterious or recessive traits. … Crossbreeding between populations also often has positive effects on fitness-related traits, but also sometimes leads to negative effects known as outbreeding depression.

Why is inbreeding a problem?

Inbreeding increases the risk of recessive gene disorders Inbreeding also increases the risk of disorders caused by recessive genes. These disorders can lead to calf abnormalities, miscarriages and stillbirths. Animals must have two copies of a recessive gene to have the disorder.

Even when we can’t always see red hair, many people still carry the genes.

How can inbreeding depression be prevented?

Inbreeding depression is one of the leading factors preventing the evolution of self-fertilization in plants. In populations where self-fertilization evolves, theory suggests that natural selection against partially recessive deleterious alleles will reduce inbreeding depression.
