Non-random mating will have the lowest chance of reversing the population's anticipated loss of the b allele. Small populations typically experience a faster loss of genetic diversity than big populations due to stochastic sampling error.

A and B are the best options for 2nd question. Disruptive selection and directional selection kinds of selection may enhance the proportion of lizards with large jaws when applied to a population of reptiles with variable jaw sizes.

It is wise to select option d for 3rd question. When two species that are geographically separated from one another evolve similar traits due to natural selection acting on those traits, this is known as convergence.

This is because small populations increase the likelihood of some gene variants being lost by random chance. Selection, which boosts advantageous alleles and eliminates harmful ones, and genetic drift, which changes frequencies arbitrarily as some parents pass on more or fewer alleles to the following generation, are the two processes in a population without migration that alter allele frequencies.

According to our calculations, the population's predicted loss of the b allele will thus have the lowest likelihood of being reversed by non-random mating.
