We discussed the technical parameter, genetic relatedness, in detail, including its specific meaning and its causal impact in the context of the evolution of social behavior. Which of the following is (are) a true statement about genetic relatedness?

a. Genetic relatedness describes the statistical probability that an individual piece of design information in one individual is an exact copy of a piece in a second animal by virtue of having been inherited from a very recent common ancestor.

b. Genetic relatedness describes the statistical probability that cooperative help between two animals will enhance the replication of the specific pieces of information building each animal.

c. Genetic relatedness describes the statistical parameter that animals will evolve to "use" in assessing the cost/benefit of cooperation and conflict with conspecifics where conflicts of interest are involved.

d. all of the above e. a. and b.

Which of the following would most directly interfere with sperm production? ingestion of a substance that mimicked inhibin interruption of sustentocytes' production of abp low sperm count use of synthetic steroids (testosterone)

The passing on of genetic traits from parents to offspring.

Suppose a point mutation, such as a change from an adenine to a guanine, occurs in the genome of a human sperm cell. the mutation could occur in any region of a gene. the effect of the mutation on the phenotype of the offspring will be determined by where the mutation occurs and its effect on the final gene product. in which of the following scenarios could the mutation alter the phenotype of the offspring? select all of the scenarios that apply the mutation occurs in the promoter and affects the rate of gene transcription. the mutation results in a new, dominant allele the mutation occurs in a portion of an intron not responsible for exon splicing the mutation occurs in a gene that controls development and alters differentiation of a cell type during development. the mutation occurs in a codon and alters the function of the final protein e mutation occurs in a codon, and the amino acid sequence of the final protein is unchanged.
