How do epigenetic marks compare in monozygotic twins?

_____ can cause a single genotype to produce a range of potential phenotypes.

The following are differences between Next gen sequencing and Sanger sequencing (select all that apply). Only select the ones that you are sure of, as canvas takes off points for selecting an incorrect option.

If the template strand of DNA that is replicated loops on itself, the newly formed strand will have this type of mutation:

What is usually the cause for the insertion of long nucleotide repeats?

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?  

_____ can cause a single genotype to produce a range of potential phenotypes.

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 mutation is considered a change in:

Which mutation would the easiest to be detected?
