Polydactyly (extra digits) is a very rare autosomal dominant trait. A man and woman with the disorder meet at a polydactyly support group and eventually had a child together. The child was normal. What is the probability that their next child will have the extra digits?

Step 1

Let's use "P" to represent the dominant allele for polydactyly and "p" to represent the recessive allele for normal digits. The man and woman both have the disorder, so they must be heterozygous (Pp) for polydactyly. Man: Pp Woman: Pp Show more…
