Transcribed Image Text:Two inherited traits: Dihybrid Crosses
A "dihybrid" cross chart shows the probability of inheriting two specific traits from parents. We
construct this chart by finding out what the parents' genotypes are for those two traits and listing all of
the possible genetic combinations that could result. For example:
F3
John and Mary want to know what their baby might look like. John and Mary both have dimples, but
they know that they are both heterozygous for this phenotype (Dd genotype). John and Mary both have
free-hanging earlobes and they know that they are both are heterozygous for this trait (Ee genotype).
