If straight hair coat (S) is dominant over curly hair (s), can two horses with straight hair coat produce an offspring with curly hair? Explain your answer.

Answer:

Yes, two horses with straight hair can produce a curly-haired offspring if both parents are heterozygous (Ss). This means each parent carries one dominant allele for straight hair and one recessive allele for curly hair. If an offspring inherits the recessive allele (s) from both parents, it will have the genotype ss and will have curly hair.
