GENERAL KNOWLEDGE

Detailed explanation-1: -Heredity, the sum of all biological process by which particular characteristics are transmitted from parents to their offspring. the set of genes that an offspring inherits from both parents, a combination of the genetic material of each, is called the organism’s genotype. So, the correct option is ‘Heredity’.

Detailed explanation-2: -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-3: -Genomics is a more recent term that describes the study of all of a person’s genes (the genome), including interactions of those genes with each other and with the person’s environment.

Detailed explanation-4: -Heredity-the transmission of traits from parents to offspring. Environment – all outside forces, everything that an organism comes in contact with. Genetics – the science of heredity. Dominance – when one allele of a gene prevents the expression of another.
