Mendel’s Law of Segregation for Inherited Traits and Diseases

Mendel’s Law of Segregation

accounted for in Anaphase I

Mendel’s Law of Segregation states that during the formation of gametes (sex cells), the two alleles (variations of a gene) segregate from each other so that each gamete receives only one allele. This means that when two gametes fuse during fertilization, the new individual will inherit one allele from each parent in equal probability.

For example, if a plant has two alleles for flower color, one for red and one for white, during gamete formation, the alleles will segregate and each gamete will receive only one of the alleles. Therefore, half of the gametes will carry the red allele and the other half will carry the white allele.

When two gametes combine during fertilization, the resulting offspring will inherit one allele from each parent, giving the offspring a 50/50 chance of inheriting either the red or white allele. This principle also explains why genes that are responsible for inherited diseases can be passed on to children even if the parents do not show any symptoms.
