Answer
Hybrid individuals from closely related species, such as lions and tigers, are reproductively sterile due to genetic incompatibilities.
Solution
a
Chromosomal differences: Lions and tigers have different numbers of chromosomes, which can lead to issues during meiosis in hybrids
b
Gene regulation: The regulatory mechanisms for gene expression may not function properly in hybrids, leading to developmental issues
c
Epigenetic factors: Differences in DNA methylation and histone modification patterns can affect gene expression in hybrids, contributing to sterility
Key Concept
Genetic incompatibilities
Explanation
Genetic differences between closely related species can lead to issues in meiosis, gene regulation, and epigenetic factors, resulting in reproductive sterility in hybrid individuals.
