A mutation is considered a change in:

A sunflower population has a mean of 100 days to flowering. Two parents were selected that had a mean of 70 days to flowering. The quantitative trait “days to flowering” has a heritability of 0.4. What would be the mean of a population derived from crossing these two parents? h2=R/S

In an experimental population of Tribolium(flour beetles), the body length shows a continuous distribution with a mean of 6mm. A group of males and females with body lengths of 9 mm are interbred. The body lengths of their offspring average 8.1 mm. If they select individuals of 12 mm to interbreed, which will be the average length of their offspring?

What would the following mutation in the coding strand cause? 5 -ATG ACG TTT GAA ATT CAG TCT AGA-3 5 -ATG ACG TTT GAA ATT TAG TCT AGA-3    

Through which of the following methods are we able to determine with certainty the function of a particular DNA segment?

After how many cell replication events will a mutation be present in both strands of DNA (replicated mutation)?

A  strain of grain has variation in oil content . Diploid grain oil content is influenced by four genes (A or a through D or d) with two additive alleles each. Each of the genes contributes equally. The highest-producing strain has 24% oil content; the lowest has 0%. Which of the following genotypes would have on average 9% oil content?

Using the following figure, what would likely happen to transcription if a certain consensus sequence within region A is deleted?

The following are true statements about mutations except:

Consider a gene in mice that is maternally imprinted. What would be the phenotype of the offspring for the trait encoded by this gene?
