Mendel's Monohybrid Crosses and First Law

Mendel's First Law

Mendel's first law states that for the pair of alleles an individual has of some gene (or at some genetic locus), one is a copy of a randomly chosen one in the father of the individual, and the other is a copy of a randomly chosen one in the mother, and that a randomly chosen one will be copied.

When Mendel conducted his monohybrid crosses, he observed the patterns of inheritance for a single trait. Through his experiments with pea plants, he developed the first law of segregation. This law describes how alleles segregate during the formation of gametes, ensuring that each gamete receives only one allele for each gene.

According to Mendel's first law, each parent contributes one allele for a particular trait to their offspring. These alleles segregate independently during gamete formation, leading to a random combination of alleles in the offspring. This principle of segregation is essential for understanding patterns of inheritance in genetics.

Overall, Mendel's first law of segregation laid the foundation for modern genetics and helped explain the inheritance of traits from one generation to the next.
