The term for a cross that involves just on trait, such as pod shape, is called a
A
homozygous cross
B
test cross
C
monohybrid cross
D
dihybrid cross
Explanation: 

Detailed explanation-1: -“A monohybrid cross is the hybrid of two individuals with homozygous genotypes which result in the opposite phenotype for a certain genetic trait.” “The cross between two monohybrid traits (TT and tt) is called a Monohybrid Cross.” Monohybrid cross is responsible for the inheritance of one gene.

Detailed explanation-2: -Monohybrid cross refers to inheritance of a single contrasting trait by two parents at a time.

Detailed explanation-3: -Fertilization between two true-breeding parents that differ in only one characteristic is called a monohybrid cross. For a monohybrid cross of two true-breeding parents, each parent contributes one type of allele resulting in all of the offspring with the same genotype.

Detailed explanation-4: -A monohybrid test cross is the process by which you cross two organisms that are heterozygous for a given trait. In such a case, by the law of dominance and by using the Punnett square, you know that the proportion of the offspring produced will be 25% homozygous dominant, 50% heterozygous and 25% homozygous recessive.

Detailed explanation-5: -A monohybrid cross is a cross between two organisms with different variations at one genetic locus of interest. The character(s) being studied in a monohybrid cross are governed by two or multiple variations for a single location of a gene.
