How To Do a Dihybrid Cross Dihybrid Cross Examples Lesson Summary Frequently Asked Questions What is a Dihybrid cross in biology? It is the exchange of (or cross of) the genetic material between two organisms that have heterozygous genes for the same two traits. A dihybrid cross is the ...
5.to form a double-stranded nucleic acid of two single strands of DNA or RNA, or one of each, by allowing the base pairs of the separate strands to form complementary bonds. 6.to fuse two cells of different genotypes into a hybrid cell. ...

Word origin:mono– (single) Compare: dihybrid cross See also: hybridization Related term(s): monohybrid Mentioned in: Punnett Square
In the image above, amonohybrid crossis performed between plants that are heterozygous for round seed shape. The predicted inheritance pattern of the offspring results in a 1:2:1 ratio of the genotype. About one-fourth will be homozygous dominant for round seed shape (RR), half will be hete...
It is typically applied inmonohybrid crossesand dihybrid crosses in which the theoretical outcomes are based on the assumptions ofsegregationandindependent assortmentof alleles (according toMendelian inheritance). Deviations from the expected outcomes are observed in the following conditions: ...
known as a dihybrid cross, there will usually be two vertical and two horizontal lines within the larger square instead of one of each, creating 16 smaller squares instead of four. In a trihybrid cross, the Punnett square will be eight squares by eight squares. (See Resources for examples)...
Nondisjunction is the improper separation of chromosomes during cell division. The result of nondisjunction is aneuploidy, which is when cells contain either an extra or missing chromosome. In contrast, euploidy is when a cell contains the normal chromosome complement. ...
