What is the law of inheritance.....?? |
| Answer» Mendel conducted experiments on seven characters of pea plants to explain inheritance. He put forth main laws of inheritance which comprised 4 independent laws.Law of unit characters: All the characters of an individual are stored in gametes in the form of factors present on the chromosomes. These factors are referred to as genes. Genes are located at a particular locus on the homologous pair of chromosomes. Genes are responsible for traits of an individual.Law of dominance: According to the principle of dominance, only one member of the pair of characters is expressed by suppressing the recessive character. The expressed character is called as dominant character.Law of segregation: during hybrid formation, two unlike factors do not lose their identity. During gamete formation, they segregate from one another and redistribute themselves in next generation.Law of independent assortment: When two pairs of independent alleles are brought together, they exhibit independent dominant effects. During gamete formation, genes of different characters are independent of one another. | |
