ANY HELP ON THE BELOW QUESTIONS THAT I'M STUCK ON WILL HELP SO MUCH! THANKS!

1. What are paralogous genes?

2. Genes that are found on the same chromosome are:

3. When comparing genes from two sequenced genomes, how does one determine whether two genes are orthologous?

4. Natural selection that favors intermediate phenotypes and acts against extremes at either end of the phenotypic spectrum in a population is known as _______.

5. Mexican hairless dogs are heterozygous (Hh), carrying a single copy of the recessive lethal allele. In a given population, the Hh genotypic frequency is 60% and the frequency of each homozygote is 20%. Assuming w = 1 for the Hh and hh dogs, what is the estimated genotypic frequency of the lethal HH genotype after reproduction?

6. The coefficient of inbreeding (F) can be used to estimate the proportion of loci that are

7. Identify the evolutionary forces that can cause allele frequencies to change from one generation to the next.

Check all that apply.

8. Which of the following best describes how natural selection can produce balanced polymorphism of allele frequencies through selection that favors heterozygotes?

Thank you in advance!!

a. genes that are derived from a duplication event b. genes in different species that are derived from a single common ancestral gene c. unrelated genes that encode similar functional products d. genes that encode antagonistic functions

Explanation / Answer

1. a. genes that are derived from a duplication event

If a gene raised by duplication in some species, the resulting genes are paralogs of each other, they may become structurally and functionally different over time.
