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.
