<u>Cross the </u><u>green-pod plant</u><u> with a yellow-pod plant. </u>Because the homozygous recessive plant tests for the presence of any recessive alleles in the unknown genotype.
The cross between an unknown genotype plant and a known homozygous recessive plant is referred to as a test cross. Because each offspring of a recessive homozygote will inherit one allele for the recessive trait, the phenotype of the offspring will depend on the second allele.
The genotypes, allele combinations, and observable qualities of children from genetic crosses may be predicted using a Punnett square. Mendel examined the genetics of pea plants and determined how traits like flower color, blossom position, seed color, and seed shape are passed down through the generations.
According to Mendel's theory, parents impart "heritable factors"—what we now refer to as genes to their children, which in turn determines their qualities. A particular gene, such as the Y gene below, which determines seed color, has two copies in every individual. If these copies correspond to various alleles, or versions, of the gene, the dominant allele may conceal the recessive allele. The dominant yellow allele Y conceals the recessive green allele Y in seeds.

Answer: In order for cells to function and survive, these organelles work together to carry out specific tasks, and perform specific roles. Each organelle has its own role that contributes to the survival of the cell.
Explanation:
Answer:
A disease that is not contagious is called a noninfectious disease. These diseases are not caused by pathogens. Instead, they are likely to have causes such as lifestyle factors, environmental toxins, or gene mutations. Common types of noninfectious diseases include cancer, diabetes, and immune system diseases.
