Suppose that allele D produces tiny ears and allele d produces normal ears. A heterozygous male with the Dd genotype mates with a homozygous female with the dd genotype. Tiny ears is an autosomal dominant trait expressed with 50%50% penetrance. Determine the probability that their offspring will have tiny ears. Report your answer as a percentage without decimal point

Penetrance in genetics refers to the percentage of individuals with a specific genotype (gene combination) who actually express the associated phenotype (physical traits). In other words, it measures the relationship between a person's genetic make-up and the expression of a particular trait.
A trait with complete penetrance is expressed in all individuals who carry the associated gene, whereas a trait with low penetrance may only be expressed in some individuals carrying the same gene.
