Question 5
F1 generation genotype is: BbTt
chestnut pacer genotype (double recessive) is : bbtt
Cross:
F1 generation black trotter x chestnut pacer
BbTt x bbtt
Use a Punnett square diagram to determine the predicted outcome of this cross:
Thus the predicted phenotypes and their expected ratios are as follows:
black trotter = 1 (25%)
black pacer = 1 (25%)
chestnut trotter = 1 (25%)
chestnut pacer = 1 (25%)
