Answer
Genetic Bottleneck
Solution
a
Genetic Drift: A severe reduction in population size can lead to genetic drift, where allele frequencies change randomly, potentially reducing genetic variation
b
Inbreeding: With a smaller population, individuals are more likely to mate with relatives, increasing the chances of inbreeding and the expression of deleterious alleles
c
Reduced Genetic Diversity: The population may experience a loss of genetic diversity, making it less adaptable to environmental changes and more susceptible to diseases
Key Concept
Genetic Bottleneck
Explanation
A genetic bottleneck occurs when a population's size is significantly reduced for at least one generation, leading to a loss of genetic variation and potential long-term effects on the population's survival and adaptability.
