What are Mendel's Laws of Genetics?
1. Law of Segregation
2. Law of Independent Assortment
3. Principle of Dominance
Mendel's Laws of Genetics
Mendel's Laws of Genetics are fundamental principles that govern the inheritance of traits in living organisms. These laws were discovered by Gregor Mendel, an Austrian monk who conducted groundbreaking experiments with pea plants in the 19th century.
1. Law of Segregation: This law states that when gametes are formed, alleles are separated so that each gamete carries only one allele for each gene. This ensures that offspring receive one allele from each parent.
2. Law of Independent Assortment: According to this law, the segregation of alleles for one gene occurs independently of that for any other gene. In other words, the inheritance of one trait does not affect the inheritance of another trait.
3. Principle of Dominance: This principle dictates that recessive alleles will be masked by dominant alleles. In cases where an individual carries both dominant and recessive alleles for a particular trait, the dominant allele will be expressed in the phenotype.
By understanding Mendel's Laws of Genetics, we can predict and explain the patterns of inheritance seen in offspring and gain insights into the mechanisms of genetic inheritance.
