Genetics: Exploring Mendel's Laws Through Crosses

What are Mendel's laws and how are they demonstrated in genetic crosses?

The two fundamental principles in genetics, known as Mendel's laws, are the Law of Segregation and the Law of Independent Assortment. How are these laws demonstrated in genetic crosses?

Mendel's Laws and Genetic Crosses

Mendel's laws are essential in understanding how traits are inherited. The Law of Segregation states that during gamete formation, alleles for a trait separate and each gamete receives only one allele. This law is demonstrated in mono-hybrid crosses, which involve the inheritance of a single trait.

The Law of Independent Assortment, on the other hand, states that alleles for different traits segregate independently during gamete formation. This law is demonstrated in dihybrid crosses, which involve the inheritance of two different traits.

By exploring genetic crosses, we can observe how these laws play a crucial role in the inheritance of traits and the variation in offspring.
