* Dihybrid: This refers to the inheritance of two different traits. For example, seed color and seed shape in pea plants.
* Heterozygous: This means the organism has two different alleles for each of these traits. An allele is a specific version of a gene. For example, one allele for seed color might be "yellow" (Y) and the other might be "green" (y).
Example:
A pea plant that is dihybrid heterozygous for seed color and seed shape would have the following genotype:
* YyRr
* Yy: Heterozygous for seed color (yellow allele 'Y' and green allele 'y')
* Rr: Heterozygous for seed shape (round allele 'R' and wrinkled allele 'r')
In summary, a dihybrid heterozygous organism inherits two different alleles for two different genes, making it a carrier of multiple traits.
