Incorrect Statement:
Inbreeding selects harmful recessive genes that reduce fertility and productivity.

Explanation:
Inbreeding refers to the mating of individuals who are closely related to each other, such as siblings or cousins. This practice leads to an increase in homozygosity, which means that individuals inherit two copies of the same allele for a particular gene. While inbreeding can have certain benefits, such as the accumulation of superior genes and the elimination of undesirable genes, it also has some negative consequences.

Inbreeding Increases Homozygosity:
Inbreeding does lead to an increase in homozygosity. This is because mating between closely related individuals increases the likelihood of inheriting identical alleles from both parents. As a result, the genetic diversity within a population decreases, and the frequency of homozygous individuals increases.

Inbreeding is Essential to Evolve Purelines:
Inbreeding is indeed essential to evolve purelines in any animal. Purelines are populations of individuals that are genetically uniform for a particular trait. Through inbreeding, individuals with desirable traits can be selectively bred to create a population that consistently exhibits those traits. This is commonly practiced in animal breeding to establish and maintain specific breeds with distinct characteristics.

Inbreeding Helps in Accumulation of Superior Genes and Elimination of Undesirable Genes:
Inbreeding can help in the accumulation of superior genes and the elimination of undesirable genes. By selectively breeding individuals with desirable traits, those traits can be concentrated within the population. Undesirable genes, such as those responsible for certain diseases or defects, can also be identified and eliminated through inbreeding.

Incorrect Statement: Inbreeding Selects Harmful Recessive Genes that Reduce Fertility and Productivity:
This statement is incorrect. Inbreeding does increase the risk of homozygosity for harmful recessive genes, which can lead to the expression of genetic disorders or reduced fertility and productivity. However, inbreeding itself does not actively select for these harmful genes. Instead, it increases the chances of them being inherited due to the limited genetic diversity within the population. Natural selection, on the other hand, plays a role in the elimination of individuals with reduced fitness, including those carrying harmful recessive genes.

In conclusion, the incorrect statement is option C: "Inbreeding selects harmful recessive genes that reduce fertility and productivity." While inbreeding can increase the risk of harmful recessive genes being expressed, it does not actively select for them. However, inbreeding can be used to accumulate superior genes and eliminate undesirable genes, making it an important tool in animal breeding for the development of purelines.
