Final answer:

Mendel discovered specific patterns in the inheritance of traits, pinpointing the presence of dominant and recessive alleles, and understanding how heritable factors (genes) are passed from parents to offspring.

Step-by-step explanation:

Mendel discovered there are laws to the ways that traits emerge in new plants. Through his experiments with pea plants, Mendel observed that when crossing plants that differed in one trait, the F1 offspring all expressed the dominant trait, while the F2 generation revealed the recessive trait in a predictable 3:1 ratio. He concluded that the traits were determined by heritable factors, now known as genes, which were passed on from both parents to the offspring. Mendel's careful breeding and observation led to the discovery of the principles of heredity, including the concepts of dominant and recessive alleles, segregation, and independent assortment.

Answer:

2 laws

Step-by-step explanation:

Mendel's work on inheritance led to the discovery of "laws" or principles that describe the ways traits emerge in plants and other organisms. Specifically, Mendel formulated two fundamental laws:

1. Law of Segregation: This law states that an individual has two alleles for each gene, one inherited from each parent. During the formation of gametes (sperm and egg cells), these alleles segregate (separate) so that each gamete carries only one allele for each gene.

2. Law of Independent Assortment: This law states that the alleles of different genes segregate independently of each other during gamete formation. In other words, the inheritance of one gene does not affect the inheritance of another gene.
