A horse breeder has a stallion with a curly coat caused by a dominant mutation. The stallion is heterozygous (CcCcCc). The breeder crosses this stallion with a straight-coated mare, who is homozygous recessive (cccccc).
Draw a Punnett square diagram to show this genetic cross. Use the following symbols:
Identify the expected genotypes of the offspring, state their corresponding phenotypes, and determine the probability that an offspring will have a curly coat.
