Answer 2

The answers are given below:

• Mendel did the monohybrid cross and test cross.
• Mendel experimented by crossing a tall and short plant of a pea. To his surprise, all the plants obtained in the first(F1) generation were tall.
• Mendel came out with three laws, the Law of Dominance, the Law of segregation, and the law of Independent Assortment.
• Law of dominance: When the parents have pure and contrasting features, their phenotype will have only one parent's features that are the dominant ones.
• Law of Segregation: Each gamete carries only one allele for each gene which is formed by the separation of each gamete.
• Law of Independent Assortment: According to the law, the alleles of two or more genes are sorted into independent gametes.
