Inbreeding

Inbreeding. Inbreeding. inbreeding coefficient F – probability that given alleles are identical by descent - note: homozygotes may arise in population from unrelated parents but : generally will have less overall homozygosity by random chance than from inbreeding . Inbreeding.

Lecture 6: Inbreeding and Heterosis

Lecture 6: Inbreeding and Heterosis. Inbreeding. Inbreeding = mating of related individuals Often results in a change in the mean of a trait Inbreeding is intentionally practiced to: create genetic uniformity of laboratory stocks produce stocks for crossing (animal and plant breeding)

Inbreeding and Outbreeding

Inbreeding and Outbreeding. Inbreeding. Occurs when close relations bred together. Used by breeder to reinforce desirable characteristics. Can increase the likely hood that an individual might inherit 2 copies of a recessive allele. Therefore recessive genetic diseases are more likely.

Selective breeding, inbreeding and hybridization

Selective breeding, inbreeding and hybridization. By: M aayan and Alex N. Selective breeding : Mating 2 different organisms to create a new organism with both traits of the parents. Advantages: You get the desired traits that you wanted. Ex. Fur, products made by the animal, strength.

Lab 4: Inbreeding and Kinship

Lab 4: Inbreeding and Kinship. Inbreeding. Reduces heterozygosity Does not change allele frequencies. Inbreeding: Breeding between closely related individuals. The inbreeding coefficient (f ) can be calculated by: . H f = Heterozygosity observed in a population experiencing inbreeding .

General analysis of inbreeding

General analysis of inbreeding. Self-fertilization and sibling mating most extreme forms of inbreeding, but matings between more distant relatives (e.g. cousins) has same effect on frequency of homozygotes, but rate is slower. General analysis of inbreeding.
