write a short note on genes as a unit of inheritance
Answers
Answer:
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. ... Every person has two copies of each gene, one inherited from each parent.
Chromatin reticulum [thread like structures inside a nucleus] condenses to form structures called as chromosome. The chromosome contain genes
which helps in inheritance of the parental traits from the parents to the offsprings. Offsprings contain the sum of the chromosomes in the parents. Genes further contain DNA (deoxyribonucleic acid).
individual with beneficial characteristics indirectly have their offsprings this is a merit of genitive transmission .Genetic variations that alter gene activity or protein function can introduce different traits in an organism.
