In a breeding experiment, a dihybrid cross is made up of two organisms that are identical hybrids for two traits. In other words, a dihybrid cross is a cross of two organisms that are heterozygous for two separate features. The individuals that exhibit this type of trait are homozygous for a specific trait. It is the DNA segments called genes that determine these traits. Each trait's parents in a dihybrid cross have a unique pair of alleles. While one parent carries the homozygous dominant allele, the other one contains the homozygous recessive allele. All of the F1 generation's offspring are heterozygous for particular features after the crossings. A prime example of a dihybrid cross is Mendel's experiment with peas. The goal of the experiment was to determine whether any relationships between different pairs of alleles exist. If you or your kids are struggling with this concept in Biology, please don’t be worried, we have provided these free dihybrid cross worksheets for extra practice. These biology worksheets include various types of exercises like determining the genotypes of the parents or answering questions about the probability of obtaining various offspring. If you are looking for a way to re-teach and provide additional practice with dihybrid crosses, give our dihybrid cross worksheets a try. We’re sure that it would be a great reinforcement activity.
