Insertion Mutations. What is an insertion mutation?. Mutations caused by the insertion of DNA bases or fragments This can happen when DNA is copied incorrectly ( frameshift mutation) One or two bases are added This can also happen when large fragments move from one place to another.
2. a) 0.25 (both are HRHW, 0.50 that each pass on HR allele)
b) 0.50 ( 0.25 probability of each combination, 2 combinations produce roan cattle)
b) cross 1: 0.50; cross 2: 0.50; cross 3: 0.50
c) cross 1: 0.00; cross 2: 0.50; cross 3: 0.25
b) affected son: 0.25 (50% mom is a carrier x 50% she will pass on alllele); affected daughter: 0.25
a) left handed child: 0.50
b) left handed with brown eyes: 0.50 (probability of brown eyes is 1.00)
6. Condition is recessive; 0.50 that carrier female will pass on affected allele, 0.67 that man is a carrier, 0.50 that man will pass on affected allele
0.50 x 0.67 x 0.50 = ~ 0.18 that they will have an affected child.
