please explain Mendol's law
Answers
✳Mendel conducted hybridization experiments on the garden peas for 7 years (1856-1863) and proposed the laws of inheritance in living organism.
➡Based on his observations on monohybrid cross (Inheritance of one gene) , Mendel proposed two rules to consolidate his understanding of inheritance in monohybrid crosses.
✴Today these rules are called Principles or Laws of Inheritance : the First Law or Law of Dominance and the second Law or Law of Segregation
✔Law of Dominance :
The Law of Dominance states that
▶ Characters are controlled by discrete units called factors.
▶Factors occur in pairs.
▶In a dissimilar pair of factors pertaining to a character, one member of the pair dominates (dominant) the other (recessive).
✔Law of Segregation :
▶It is also called Law of Purity of Gametes.
Mendel's Law of Segregation states that "the two alleles of gene when present together in a heterozygous state, do not fuse or blend in any way ,but remain distinct and segregate during meiosis or in the formation of Gametes so that each meiotic product or gamete will carry only one of them."
➡Based on his observations on dihybrid cross(inheritance of two genes) , Mendel proposed a second set of generalizations that we call Mendel's Law of Independent Assortment.
Law of Independent Assortment :
The law of Independent Assortment states that "When two pairs of traits are combined in a dihybrid, segregation of one pair of characters is independent of the other pair of characters".
