HI! Let's try this problem. We have a pea plant that is heterozygous for two traits €” height and seed color. The plant is tall and yellow, which are the dominant phenotypes. We will let this plant self-fertilize, and see what kind of offspring this plant produces. This is a dihybrid cross; we are tracking two traits.

Dihybrid cross examples Persons who have the genotype CC are normal both genotypically. and phenotypically. Those who are Cc are phenotypically normal, but. are genotypically carriers. Persons who are cc have cystic fibrosis. The parents of a child with cystic fibrosis express disbelief because. no one in either family ever had the disease. A trihybrid plant, exhibiting independent assortment at all three loci, is self-fertilized. What is the probability that an offspring will have the dominant phenotype at all three loci?
Gregor studied inheritance by experimenting with peas in his garden. Peas work as an excellent test subject as they can self-pollinate, cross fertilize, and have several traits that only have two forms. This enabled Mendel to easily control his experiments and reduced the possibility of the outcomes to something he could record and manage. PubMed and Web of Science, two databases of academic literature, both return zero results for "trihybrid cross" (in the sense meant here) or "tetrahybrid cross", so they don't seem to be common. I guess one might carry out a trihybrid or higher order test cross for the purpose of genetic mapping. En.lifeder.com The trihybrid cross. A trihybrid cross is when there is a genetic cross involving three traits of the organisms being mated. A Punnett square can once more be used to calculate what the probabilities will be for both the genotypes and the phenotypes. For example, the ratios can be calculated for a cross between AaBbCc and AaBbCc.
