What is the probability of two heterozygous parents having a recessive offspring?What is the probability of a heterozygous offspring? There is a 50% x 50% = 25% probability that both of the alleles of the offspring are dominant. There is a 50% x 50% = 25% probability that both alleles of the offspring's are recessive.
What is the probability that two heterozygous?This is because according to Mendelian inheritance, when two heterozygotes mate, there is a 1:2:1 distribution of genotypes AA:Aa:aa. However, because #6 is unaffected, he can't be aa, so he is either Aa or AA, but the probability of him being Aa is twice as likely as AA.
What is the probability of a homozygous dominant offspring for these two parents?Above if the homozygous parent has two dominant alleles, then all of the offspring will have the same phenotype of the dominant trait. In other words, there is a 100% probability that an offspring of such a pairing will exhibit the dominant phenotype.

One Homozygous Parent.. What is the probability for two parents who are both heterozygous to have a child who exhibits the dominant trait?We know that when two people who are both heterozygous for a simple Mendelian autosomal gene alpha have a child, the probability that the child will show the dominant phenotype is 3/4.
