A different strain of grain has variation in oil content too. Diploid grain is influenced by four genes (A or a through D or d) with two additive alleles each. The highest-producing strain has 24% oil content; the lowest has 0%. What is the probable contribution to oil production from each type of allele?

The following fragment of DNA was sequenced and then treated with sodium bisulfite. Compare both sequences and determine which Cytosines were originally methylated and which were not. The presence of methylated cytosines should be indicated including an asterisk (*) after each methylated cytosine. Untreated         ACTACCATGGCGCTT Treated              ACTATCATGGCGTTT

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
