Describe Mendel's conclusions about how traits are passed from generation to generation.
A) Mendel hypothesized that traits in peas are controlled by specific unit factors. He suggested that unit factors occur in pairs and stay together during gamete formation.
B) Mendel hypothesized that traits in peas are controlled by specific unit factors. He suggested that unit factors occur in pairs and that unit factors separate from each other during gamete formation.
C) Mendel hypothesized that traits in peas are controlled by DNA sequences he called genes. He suggested that genes occur in pairs and stay together during gamete formation.
D) Mendel hypothesized that traits in peas are controlled by DNA sequences he called genes. He suggested that genes occur in pairs and members of each gene pair separate from each other during gamete formation.

Gregor Mendel was regarded "Father of Genetics" for his tremendous impact in discovering the principles that governs heredity. He performed series of experiments on pea plants. In his experiments, he discovered that the traits organisms possess is determined or controlled by specific units. These units were later discovered to be genes.

He realized that an organism receives two forms of these genes called ALLELE, one from each parent. During his crossing experiments with pea plants, he derived an hypothesis that these received alleles that make up the gene of an organism gets separated into gametes during gamete formation. He was able to come up with his Law of Segregation after this observation.
