Mendelian Inheritance
Q1: What were the three laws formulated by Gregor Johann Mendel and what do they explain?
Answer:
Gregor Johann Mendel discovered 3 laws those are:
- Law of dominance,
- Law of segregation,
- Law of independent assortment.
Q2: Why do members of the same family frequently share traits?
Answer:
Members of the same family frequently share traits because of inheritance. Individuals inherit one ‘factor’ from each parent for each trait, and genetic traits that follow Mendelian principles are passed down from generation to generation.
Q3: What are Mendelian qualities and how are they inherited?
Answer:
Mendelian qualities are genetic traits that follow the principles of Mendelian inheritance. They are inherited as one ‘factor’ from each parent for each trait. Genetic traits that follow these principles are known as Mendelian.
Q4: What is the difference between Mendelian and non-mendelian inheritance?
Answer:
Mendelian inheritance refers to the determination of qualities by dominant and recessive alleles of a given gene, whereas non-Mendelian inheritance refers to the inheritance of features that go against to Mendel’s principles.
Gregor Mendel and the Principles of Inheritance
Mendelian inheritance is an explanation for how distinct units or genes pass on traits or personalities from one generation to the next. The theory was first put out by the Austrian monk Gregor Johann Mendel, who has been considered the “Father of Genetics” in recognition of his work. He established the laws of dominance, segregation, and independent assortment as three ways to explain the idea of inheritance.
