Question

mendels law of inheritence ???

Answer 1

hi friend,
Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel's Laws of Heredity are usually stated as: 1) The Law of Segregation: Each inherited trait is defined by a gene pair.

Answer 2

ANSWER :-

To learn about the laws of inheritance proposed by Gregor Johann Mendel, we must have an idea about the postulates proposed by him first instead.

• POSTULATE 1- Every character is controlled by paired factors.
• POSTULATE 2- Postulate of dominance.
• POSTULATE 3- Postulate of segregation.
• POSTULATE 4- Postulate of independent assortment.

Mendel's fundamental laws of inheritance are structured as follows :-

1. The first and the second postulate together constitute the first law which is known as the "LAW OF DOMINANCE".
2. The third postulate on its own is the only postulate that constitutes the second law which is known as the "LAW OF SEGREGATION".
3. The fourth postulate on its own is the only postulate that constitutes the third law which is known as the "LAW OF INDEPENDENT ASSORTMENT".

EXTRAS :-

• Gregor Johann Mendel is considered to be the father of genetics.
• Gregor Johann Mendel is popularly known as G.J. Mendel among modern scientists.
• Mendel proposed four postulates and three laws completely based on his own experiments that he conducted on several plants, the main of all being Garden Pea plants.
• Three of the four postulates proposed by Mendel were applicable on both monohybrid and dihybrid types of crosses while one of them was applicable only on dihybrid crosses.
