Question

In a population of lizards, color is genetically determined. The current population has
two two phenotypes: blue and yellow. Which of the following scenarios could result
in evolution by migration?
O A disease indiscriminately reduces the population by 90%.
Birds are better able to see and therefor prey on blue lizards
The population is joined by individuals from a nearby population that has an
allele for a red phenotype.
Females preferentially mate with individuals exhibiting the blue phenotype.

Expert Solution

Step 1

Genetics is the study of heredity and genes in particular. Genetics is one of biology's major pillars, and it intersects with a variety of other fields such as agriculture, medicine, and biotechnology.

Humankind has understood the importance of heredity since the birth of civilisation and has applied its principles to the enhancement of cultivated crops and domestic animals.

In a population of lizards, half of the individuals are yellow and half are blue, according to the question. The colour is dictated by genetics. Now it's time to discuss the possibility of evolution through genetic drift.

So, let's have a look at the answer to the problem.
