Answer:
There are 50% of probabilities of getting roan cattle, WR
Explanation:
Available data:
1st Cross: Between cattle with solid white coats and cattle with solid red coats
Parental) WW x RR
Gametes) W W R R
F1) 100% WR
2nd Cross: Between two roan cattle
Parental) WR x WR
Gametes) W R W R
Punnet Square) W R
W WW WR
R WR RR
F2) Progeny genotype: 1/4 solid white-coated cattle, WW (25%)
2/4=1/2 roan cattle, WR (50%)
1/4 solid red-coated cattle, RR (25%)
There are 50% of probabilities of getting roan cattle, WR
