Question

Mantle made blank to determine if certain trait forms and their alleles were inherited together

Answer 1

The right answer is dihybrid crosses.

A dihybrid crossing is a reproduction between two organisms that differ in two traits. Individuals of this type of cross are homozygous for a specific trait.

The traits are characteristics that are determined by DNA segments called genes.
Diploid organisms inherit two alleles for each gene.
An allele is an alternative version of an inherited gene (one of each parent) during sexual reproduction.
