What is the definition of a dihybrid cross?

Simply saying it is cross that involves two traits

Explanation:

In dihybrid cross  the phenotypes of two genes are followed through the mating of individuals which carry multiple alleles at those gene loci. In other words, two genes controlling two different phenotypic traits are observed in dihybrid cross.

"Dihybrid cross",means

"di" indicates that there are two traits involved  for example A and B and

"hybrid" indicates that each trait has two different allele, for example A and a or B and b.

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.
