Selective Breeding

Question 1

What is natural selection?

Answer 1

When genetic variants for phenotype (traits) result in the animal having a better ability to survive and reproduce. Therefore population will increase.

Question 2

What is adaptation?

Answer 2

When variations that enable an animal a better chance of survival in a changing environment are passed on. This enables the animal a better chance of survival and therefore the trait is passed on and becomes more common in a specific species.

Question 3

What is selective breeding ?

Answer 3

Selective breeding is a process in which humans artificially select traits to become more prominent in groups of animals. This helps to produce animals with desirable characteristics for specific purposes.

This non random mating leads to an overall change on the genotype of the population over many generations.

Question 4

What is positive assortive mating ?

Answer 4

Mating two animals with the similar phenotypes or features in attempt to increase the occurrence of these traits in the offspring.

Question 5

What is negative assoritve mating ?

Answer 5

Mating animals with the opposite phenotype or features to increase the variety between offspring.
