Question

whats are the three laws of mendel​

Answer 1

Answer:

Mendel's Laws of Heredity are usually stated as:

1) The Law of Segregation: Each inherited trait is defined by a gene pair. Parental genes are randomly separated to the sex cells so that sex cells contain only one gene of the pair. Offspring therefore inherit one genetic allele from each parent when sex cells unite in fertilization.

2) The Law of Independent Assortment: Genes for different traits are sorted separately from one another so that the inheritance of one trait is not dependent on the inheritance of another.

3) The Law of Dominance: An organism with alternate forms of a gene will express the form that is dominant.

$\Large{\underline{\underline{\bf{Mendel's \: Laws:-}}}}$

There are three laws of Mendel. They are:

• Law of Dominance
• Law of Segregation
• Law of Independent assortment

Law of Dominance:

• (i) Characters are controlled by discrete units called factors
• (ii) Factors occur in pairs.
• (iii) In a dissimilar pair of factors one member of the pair dominates (dominant) over the other (recessive).

Law of Segregation ( Purity of Gametes):

This law is based on the fact that the alleles do not show any blending and that both the characters are recovered as in the F2 generation though one of these is not seen at the F1 stage. Though the parents contain two alleles duringgamete formation, the paired alleles separate or segregate from each other such that a gamete receives only one of the two factors..

Law of Independent assortment:

The law states that ‘when two pairs of traits are combined in a hybrid, segregation of one pair of characters is independent of the other pair of characters’.
