Question

Heredity characters are due to
(a)Chromosomes
(b)Gene
(c)Blood
(d)Placenta

Answer 1

Hint: They are the essential physical and functional unit of heredity. They’re structurally made from nucleotides called DNA. Many of the codes for important proteins help with the expression of traits and characteristics.

Complete answer:
Heredity characters are due to Gene. Heredity considered as the transmission of traits from parents to offspring. Heredity is liable for the resemblance among individuals of an equivalent species. Genes are available pairs within the same way because of the chromosomes. Each parent of a person carrying two copies of their genes and every parent passes one copy of genes to their child. This is often the rationale why the kid has many characteristics of both the parents like hair color, same eyes, etc.

Additional information:
The process of heredity is the sum of all biological procedures ending in the genesis of a new organism similar to its type and exhibiting some modifications coming from the genes and their interactions with their surroundings. Heredity is the term used for the transmission of the traits from one generation to a subsequent generation. It’s because of heredity that the offspring look almost like their parents. It also tells why dogs always give birth to puppies and not to kittens. The method of heredity is universal among all living organisms. Genetic variation refers to the variation during a population or species. Genetics is a detailed study of the heredity and variation in living organisms.

So, the correct answer is ‘Gene’.

Note: Genes control the functions of DNA and RNA. Proteins are the foremost important materials within the body which not only help by being the building blocks for muscles, connecting tissue and skin but also takes care of the assembly of the enzyme. These enzymes have an important function in conducting several chemical processes and reactions within the body. Therefore, protein synthesis is liable for all activities carried on by the body and are mainly controlled by the genes.
