Unformatted text preview: Genome sequencing and SNPs 2 2 When cytosine is deaminated, what base is incorporated on the opposite strand during DNA replication? A) C B) G C) T D) A When cytosine is deaminated, what base is incorporated on the opposite strand during DNA replication? A) C B) G C) T D) A These data are consistent with linkage betwee MEF2A and D15S120 and imply that: A. The A allele of marker D15S120 is linked to MEF2A B. The D allele of marker D15S120 is linked to MEF2A C. The A allele causes the Mef2a phenotype D. The D allele causes the Mef2a phenotype E. Both B and D are correct I. II. 1 2 1 2 mm Mm Mm mm A B C D I-1 I-2 II-1 II-2 Microsat: D15S120 Family #1 M= dominant mutation in Mef2A m= wild-type Mef2A These data are consistent with linkage betwee MEF2A and D15S120 and imply that: A. The A allele of marker D15S120 is linked to MEF2A B. The D allele of marker D15S120 is linked to MEF2A C. The A allele causes the Mef2a phenotype D. The D allele causes the Mef2a phenotype E. Both B and D are correct I.

Linkage between D15S87A and MEF2A B. Linkage between D15S87B and MEF2A C. Linkage between D15S87C and MEF2A D. Linkage between D15S87D and MEF2A E. Both B and C are correct 6 I.

The combination of alleles that makes a black, starless sneetch is lethal and the pregnancy terminates in week 5. Two yellow starless sneetches mate (Yyss) and just found out they are pregnant. What is the chance that the pregnancy will terminate in week 5? A) 75% B) 66% C) 33% D) 25% E) 0% YY, Yy = yellow yy = black SS, Ss = star ss = no star All the sneetches want their children to have stars on their bellies.
