WebIn some cases, the answer is yes. Genes that are sufficiently close together on a chromosome will tend to "stick together," and the versions (alleles) of those genes that are together on a chromosome will tend to be inherited as a pair more often than not. This phenomenon is called genetic linkage. WebMay 15, 2024 · 1. Dihybrid cross in Pea plants. An example of a dihybrid cross is the cross between a homozygous pea plant with round yellow seeds and wrinkled green seeds. The round yellow seeds are represented by RRYY alleles, whereas the wrinkled green seeds are represented by rryy. The gametes formed from these alleles are RY and ry.
