Answer:
Polygenic inheritance
Explanation:
Polygenic inheritance occurs when a genetic trait is regulated by more than one genes. All the alleles of these genes together determine the phenotype of the organism for the polygenic trait. Here, the phenotype is regulated by the total number of dominant alleles for all the genes that regulate a polygene trait.
For example, human skin color is a polygenic trait. The final phenotype depends on the total number of dominant alleles of all the genes that regulate the skin color in human.
Since the means of reproduction have changed, the population of peacocks would probably start losing their pretty feather colors due to the fact that over time females would be mating with the containing the other trait (and possibly not the pretty feathers). This would then produce offspring with ugly colors but also with the desired trait. This would continue on and on until those with the desired trait outnumbered or possibly extinguished the now unnecessary vibrant feather colors.
Answer: They have a son , Les who is 9 years old and healthy with myopia but not galactosemia. Les is unaffected with galactosemia.
Explanation:
From the family story, Leah is the only child affected with galactosemia while Les is unaffected and healthy.
Hanna's father and mother have three daughters and they are Hope, Holly and Banana( from oldest to youngest).
Hanan and Harry have an only son called John.
John married Jane and they have two children, Leah and Les.
Leah is girl that is affected with galactosemia and Les who is a boy and he is unaffected with galactosemia.
Jane's mother is Hilda and she has a brother called Joe. Joe married Jen and they have a son called Les.

The preferred prey item would be frogs.
What is optimal foraging theory?
It is a theory in ecology that proposes that predating animals that get the most energy from minimal efforts are favored by natural selection.
In order words, selection forces prefer investing minimum energy in order to extract maximally available energy.
In this case, the heron needs to use the lowest time to harvest the maximum energy possible. Since all the preys offer the same amount of energy, the one that requires the lowest time would be preferable for the heron.
In other words, frogs would be the most preferable prey.
