Inbreeding strategies allow the desirable qualities of more closely related individuals to be continued within the same breed for 4-6 generations. It increases homozygosity and thus, is necessary for evolving a pureline. Inbreeding exposes harmful recessive genes that are eliminated by selection. It also helps in accumulation of superior genes and elimination of less desirable genes. Therefore, this approach where there is selection at each step, increases the productivity of inbred population. However, continued inbreeding, especially close inbreeding usually leads to reduce fertility and even productivity. This is called inbreeding depression.

Inbreeding selects harmful recessive gene that reduce fertility and productivity.
Inbreeding is the mating of individuals who are closely related, such as siblings or cousins. It can have both positive and negative effects on the genetic makeup of a population. However, the statement that inbreeding selects harmful recessive genes that reduce fertility and productivity is incorrect. Inbreeding does increase the likelihood of expressing harmful recessive genes, but it does not actively select for them.
Effects of inbreeding:
1. Accumulation of superior genes: Inbreeding can lead to the accumulation of superior genes by increasing the frequency of desirable traits in a population. If there are individuals with desirable traits, mating them with close relatives can increase the chances of those traits being passed on to the offspring.
2. Increase in homozygosity: Inbreeding increases the level of homozygosity in a population. Homozygosity refers to the presence of the same allele at a particular gene locus. This can lead to the expression of both desirable and undesirable traits, as well as an increased risk of genetic disorders caused by recessive alleles.
3. Evolution of pure lines: Inbreeding is essential to evolve pure lines, particularly in animal breeding. Pure lines are populations of animals that are genetically uniform for specific traits. Inbreeding allows for the fixation of desirable traits, resulting in a more predictable and consistent breeding stock.
4. Expression of harmful recessive genes: Inbreeding increases the chances of offspring inheriting harmful recessive genes from both parents. When closely related individuals mate, there is a higher probability of these recessive genes being expressed due to the lack of genetic diversity. This can lead to reduced fertility, decreased productivity, and an increased risk of genetic disorders.
Conclusion:
Inbreeding can have both positive and negative effects on the genetic makeup of a population. While it can lead to the accumulation of superior genes and the evolution of pure lines, it also increases homozygosity and the likelihood of expressing harmful recessive genes. However, it is important to note that inbreeding itself does not actively select for these harmful genes but rather increases the chances of their expression.
