2.Explain the relationship between the dependent and independent variable in each

B.heterozygous parent crossed with heterozygous parent

An independent variable is the potential stimulus or cause, usually directly manipulated by the experimenter, so it could also be called a manipulative variable.

A dependent variable is the response or measure of results.

So what's the relationship the between the dependent and independent variable in each

A.homozygous parent crossed with heterozygous parent
B.heterozygous parent crossed with heterozygous parent

In order to understand the relationship between the dependent and independent variables in each situation, let's break it down into separate parts:

A. Homozygous Parent crossed with Heterozygous Parent:
In this scenario, the dependent variable represents the traits or characteristics of the offspring resulting from the cross. The independent variable, on the other hand, is the genetic makeup of the parental organisms.

Homozygous means that the parent carries two copies of the same allele for a specific trait, while heterozygous means that the parent carries two different alleles for the same trait.

The dependent variable is affected by the independent variable because during the cross, the offspring inherit genetic material from both parents. The traits expressed by the offspring are influenced by the combination of alleles they receive from the homozygous and heterozygous parents.

B. Heterozygous Parents crossed with Heterozygous Parents:
Similar to the previous scenario, the dependent variable here represents the traits or characteristics of the resulting offspring. The independent variable, once again, is the genetic makeup of the parental organisms.

With both parents being heterozygous, they carry two different alleles for the same trait. The dependent variable is affected as the offspring inherit genetic material from both parents, resulting in a combination of different alleles.

In both cases, the dependent variable, which represents the traits of the offspring, is influenced by the independent variable, which is the genetic makeup of the parents. The specific combination of alleles that the offspring inherit determines the traits they will exhibit, making the dependent variable dependent on the independent variable.
