Applied Genetics: Selective Breeding

Inbreeding can help in fixing desirable traits such as high milk yields in dairy cattle.

Selective breeding is also known as random selection.

Hybrid vigour is generally increased with subsequent crossing of hybrids.

AI of a cow involves inserting the semen into the horns of the uterus.

One advantage of AI mentioned in the text is the lower risk of inbreeding compared to using a stock bull.

Genotyping controls traits like milk production and carcass weight through the study of animal hormones.

In cloning, the egg cell from sheep 2 has its nucleus removed and is then fused with a somatic cell from sheep 1 using an electrical current.

Superovulation refers to the production of fewer than the normal number of mature eggs at one time.

Micropropagation is a process that produces genetically different plants from small pieces of plant tissue.

Transgenic species are organisms that have part of the DNA of another species transferred into their own DNA through genetic engineering.
