Assertion : Inbreeding increases homozygosity in animals.
Reason: Outbreeding always results in heterozygosity in animals.
Both assertion and reason are true, and the reason is the correct explanation of the assertion.
Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
The assertion is true, but the reason is false.
The assertion is false, but the reason is true.
The assertion states that inbreeding increases homozygosity in animals, which is true. Inbreeding involves mating between closely related individuals, which increases the chances of homozygous genotypes by promoting the inheritance of the same alleles from both parents.
The reason states that outbreeding always results in heterozygosity in animals, which is false. While outbreeding can introduce genetic diversity and increase the chances of heterozygous genotypes, it does not always guarantee heterozygosity. In some cases, outbreeding may still result in homozygous genotypes depending on the genetic makeup of the individuals involved.
Hence, option 3 is the correct answer.
