Why does the genetic composition of sex cells of an individual vary since the genome of an individual is same throughout his/her body.
The genetic code in each somatic cell of a eukaryote organism is identical due to mitosis. This is cell division that reproduces the genetic code of a cell. Mitosis produces new cells with copies of each chromosome, one for one.hivesaeed4 said:Why does the genetic composition of sex cells of an individual vary since the genome of an individual is same throughout his/her body.
The genetic composition of sex cells is different because of a process called meiosis. During meiosis, the chromosomes of the parent cell undergo recombination, resulting in a unique combination of genetic material in each sex cell.
The variation in genetic composition of sex cells is essential for genetic diversity in offspring. It allows for the combination of different traits from both parents, increasing the chances of survival and adaptation to changing environments.
Yes, external factors such as radiation, toxins, and drugs can cause mutations in the genetic material of sex cells, leading to changes in the genetic composition. These changes can be passed on to offspring and may have significant impacts on their health and development.
Fertilization combines the genetic material of two sex cells, resulting in a unique genetic composition in the offspring. This process further increases genetic diversity and can lead to new traits and characteristics not present in either parent.
Yes, genetic disorders can occur due to variations in the genetic composition of sex cells. These variations can be inherited and passed on to offspring, resulting in conditions such as Down syndrome, sickle cell anemia, and cystic fibrosis.
