Why does an individual have some characteristics from the father and some from the mother?
Answers
Explanation:
because the new organism is formed by the fertilization of both the parents. The male gamete i.e sperm cell has X&Y chromosomes and female gamete i.e an egg has X&X chromosomes. So due to the fusion of male and female gametes sometimes the X chromosome combines with Y chromosome and sometimes X chromosome combines with Y chromosome which decides the gender of the new individual. it also decides the characteristics of the baby like eye colour, hair colour etc.
Answer:
The process by which the characteristics are transmitted from parents to their offspring is called Heredity.
The set of genes that an offspring inherits from both parents which is the combination of the genetic material of each is called the organism's genotype.
In humans, there are 22 chromosomes pairs (autosomes) + a pair of sex chromosomes.
In males, the sex chromosome is XY and in females, it is XX.
These X and Y chromosomes and other chromosomes carry genes.
These genes contain traits or characters of the mother and father.
When a sperm fuses the ova to form the zygote or future embryo these genes from both mother and father combine together which determine the characteristics in the baby.
