Why did Mendel study pea plants?
Pea plants were easy to grow, had short generation times, produced many offspring, and showed clear contrasting traits that Mendel could study through controlled breeding.
Before testing the pea plants, Mendel formed a five-part hypothesis. What did Mendel include in his hypothesis? Check all that apply.
A plant heterozygous for yellow pod color (Yy) is crossed with a plant homozygous for green pod color (yy). Which trait is dominant?
Mendel studied pea plants for particular traits. When observing the results of his experiments, he created two laws of inheritance. How is a scientific law formed?
A scientific law is formed when repeated observations and experiments consistently support a pattern or relationship in nature.

What is the definition for "hypothesis"?
If a plant with purple petals (PP) is crossed with a plant with white petals (pp), what is the phenotype for the F1 generation?
The law of states that traits are passed from parents to offspring independently of one another.
independent assortment
Explain how the alleles were passed from parents to offspring.
The Gg parent passed a G allele, and the gg parent passed a g allele. The offspring received Gg, so they had green pods.

A plant TT for tall height is crossed with a plant tt for short height. The offspring have the genotype Tt. What is the phenotype of the plant? tall heightshort heightTttt
The law of explains how alleles separate during gamete formation.
