Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How are genetic traits passed down from generation to generation?
A
chromosomes
B
DNA
C
genes
D
reproduction
Explanation: 

Detailed explanation-1: -One copy is inherited from their mother (via the egg) and the other from their father (via the sperm). A sperm and an egg each contain one set of 23 chromosomes. When the sperm fertilises the egg, two copies of each chromosome are present (and therefore two copies of each gene), and so an embryo forms.

Detailed explanation-2: -Like chromosomes, genes also come in pairs. Each of your parents has two copies of each of their genes, and each parent passes along just one copy to make up the genes you have. Genes that are passed on to you determine many of your traits, such as your hair color and skin color.

Detailed explanation-3: -Heredity is a process in which organisms acquire characteristics from their parents. These characteristics are called traits. Every individual is unique because they have a unique set of traits. The traits which are transmitted by the parent to its offspring during the process of fertilization are inherited traits.
