Verified
In humans, an individual who has wavy hair is a heterozygote with one curly hair allele and one straight hair allele. Indicate the phenotypic and genotypic ratios expected for the offspring from a straight-haired man and a wavy-haired woman.
Heterozygote
An organism having two different alleles of a specific gene, resulting in a mixed genotype.
Phenotypic
Relating to the observable characteristics or traits of an organism, which result from the interaction of its genotype with the environment.
Genotypic
Relating to the genetic constitution of an organism, defining its specific set of genes.
- Predict phenotypic and genotypic ratios in offspring from given parental genotypes.

Final Answer :
Straight and curly hair are incompletely dominant variations. The man's genotype would be H1H1 and the woman's genotype would be H1H2. This would produce a phenotypic ratio of 50% straight hair and 50% wavy hair. The genotypic ratio would be 50% H1H1 and 50% H1H2.
