Answer 2

Answer: Heredity is controlled by molecules called Chromosomes

Explanation:

• Heredity is the process by which certain characters are transferred from the parents to their offspring like height, skin colour, facial features etc.
• This information that is carried from one generation to another is carried through genes that are present on the chromosomes.
• Chromosomes are present inside the nucleus of a cell and are replicated during cell division.
• Due to replication, each cell receives its own set of chromosomes.
• Every human being has 23 pairs of chromosomes of which 22 pairs of chromosomes are called Allosomes and the 23rd pair of chromosomes is called the sex chromosome or the autosome.
