Detailed explanation-1: -Chromosomes are thread-like structures present inside the nucleus of the cell. They are made up of the genetic material DNA, which is involved in the transmission of characters from parents to offsprings.

Detailed explanation-2: -The chromosomes are responsible for heredity transmission. These found in the nucleus of plants and animal cells.

Detailed explanation-3: -DNA (deoxyribonucleic acid) is the cell’s genetic material, contained in chromosomes within the cell nucleus and mitochondria. Except for certain cells (for example, sperm and egg cells and red blood cells), the cell nucleus contains 23 pairs of chromosomes.

Detailed explanation-4: -In a pair of chromosomes, one chromosome is always inherited from the mother and one from the father. This means that, with the exception of genes on the sex chromosomes of males, we have two copies of each gene, one inherited from our mother and one from our father.

Detailed explanation-5: -The classical principles of genetics were deduced by Gregor Mendel in 1865, on the basis of the results of breeding experiments with peas. Mendel studied the inheritance of a number of well-defined traits, such as seed color, and was able to deduce general rules for their transmission.
