Inbreeding and its effects
1. Inbreeding increases homozygosity:
- Inbreeding refers to the mating between individuals who are closely related, such as siblings or cousins.
- It leads to an increase in homozygosity, which means that the offspring inherit two copies of the same allele for a given gene.
- Homozygosity can be advantageous if the allele is beneficial, as it increases the expression of favorable traits.
- However, it can also be disadvantageous if the allele is harmful, as it increases the expression of detrimental traits.
2. Inbreeding hides harmful recessive genes:
- In a population, harmful recessive genes are often present but hidden in heterozygous individuals.
- Inbreeding increases the probability of mating between carriers of the same recessive gene, resulting in homozygosity for that gene in the offspring.
- This leads to the expression of harmful traits associated with the recessive gene.
- Inbreeding, therefore, does not hide harmful recessive genes, but rather increases their expression and reduces the ability of natural selection to eliminate them from the population.
3. Inbreeding and accumulation of inferior genes:
- Inbreeding can lead to the accumulation of inferior genes in a population.
- When closely related individuals mate, there is a higher chance of inheriting deleterious alleles.
- Over time, this can result in the accumulation of harmful genetic variations, leading to reduced fitness and increased susceptibility to diseases or other negative traits.
4. Inbreeding and evolution of pure-line:
- Inbreeding is not necessary for the evolution of a pure-line in any animal.
- A pure-line refers to a population that is homozygous for a particular trait or set of traits.
- While inbreeding can increase homozygosity, other breeding methods, such as selective breeding, can also be used to develop pure-lines without the negative consequences associated with inbreeding.
- In fact, excessive inbreeding can lead to reduced fertility, increased susceptibility to diseases, and decreased overall fitness in the population.
Conclusion:
Based on the given statements, option B is correct. Inbreeding does increase homozygosity but also leads to the expression of harmful recessive genes and the accumulation of inferior genes. However, inbreeding is not necessary for the evolution of a pure-line and can have detrimental effects on the population.

Based on the given statements, option B is correct. Inbreeding does increase homozygosity but also leads to the expression of harmful recessive genes and the accumulation of inferior genes. However, inbreeding is not necessary for the evolution of a pure-line and can have detrimental effects on the population.
