How do These Traits Get Expressed?
- The DNA present in the cells serves as a source of information for synthesizing proteins. A gene is a segment of DNA that provides the instructions for making a specific protein.
- Every cell contains a pair of each chromosome, with one chromosome inherited from each parent. During germ cell formation, each germ cell acquires one chromosome from each pair, randomly inherited from either the mother or the father. When two germ cells combine during fertilization, they restore the original number of chromosomes in the offspring, ensuring the stability of the species’ DNA.
