Answer :
When an egg and sperm form an embryo, the offspring that is formed will have genetic traits that are passed on from two parents.
When two haploid gametes fuse, a diploid embryo is formed with characteristics from both parents.
To create a fetus,. Each egg and sperm have half a pair of chromosomes. The egg and sperm combine to give the baby a complete set of chromosomes. As a result, half of the baby's DNA emerges from the mother and half from the father.
When one copy of a gene is acquired from the mother (via the egg) while the other comes from the father, the offspring inherit both copies (via the sperm). Each sperm and egg has one pair of 23 chromosomes. When the sperm fertilizes an egg, two replicas of each chromosome (and thus two replicas of each gene) are present, and an embryo is formed.
A genetic trait, as it relates to genetics, is a unique feature of an individual. Genes, environmental factors, or a combination of both parents can influence traits. Qualitative traits (such as eye color) and quantitative traits (such as height or blood pressure).
