Understanding the Three Laws of Inheritance in Genetics

Explore the three fundamental laws of inheritance established by Gregor Mendel and their significance in classical genetics.

The three laws of inheritance are: Law of Segregation (each inherited trait is defined by a gene pair, which segregates into gametes), Law of Independent Assortment (genes for different traits assort independently of each other), and Law of Dominance (dominant alleles mask recessive ones). These principles, established by Gregor Mendel, form the foundation of classical genetics.

FAQs & Answers

  1. What is the Law of Segregation? The Law of Segregation states that each inherited trait is defined by a pair of genes, which segregate into gametes during reproduction.
  2. How does the Law of Independent Assortment work? The Law of Independent Assortment asserts that genes for different traits assort independently of each other during gamete formation.
  3. What is the significance of the Law of Dominance? The Law of Dominance explains that dominant alleles can mask the effects of recessive alleles in a heterozygous genotype.
