The right option is; C. They are controlled by more than one gene
Traits such as skin color, human height and eye colour are known as polygenic traits. These traits have wide variation throughout the human population and are controlled by two or more genes. For example the human height is controlled by at least three genes with six alleles. The quantities of the genes are usually large but often have a little effect.
A the frenquency increases
Answer: Option A ,Band C.
Explanation:
Sympatric speciation is the evolution or isolation of new species from the original populations of species occupying in the same geographical area. Sympatric speciation commonly occur due to sexual selection of mates can cause reproductive barriers or isolation which keep gene pools separate. A plant with extra set of homologous chromosomes is an example of sympatric speciation.
Answer:
They are called psycrophiles or cryophiles.
