Answer:
variable expressivity; incomplete penetrance
Explanation:
In genetics, variable expressivity refers to the fact that individuals having the same alleles/genes/genotype associated with a particular genetic condition may exhibit different clinical features of this condition. In general, variable expressivity is due to the combination of both genetic and environmental factors. An example of variable expressivity is the Marfan syndrome, where all individuals with this disorder have a dominant mutation in the FBN1 (fibrillin 1) gene and show different degrees of the same phenotype. Moreover, incomplete penetrance (also known as reduced penetrance) refers to the complete absence of a genetic trait or disease in individuals having alleles/genes/genotype associated with the condition. In consequence, individuals with incomplete penetrance do not develop features of the disease. An example of incomplete penetrance is given by those individuals with mutations in BRCA1/BRCA2 genes (associated with an increased risk of developing breast cancer) that do not develop cancer.
Answer:
Somatic cells helps in healing and repairing damaged cells
Explanation:
Somatic cell division plays an important role in division of body cells. They help in healing and repairing the damaged cells. cell division is of two types, Mitosis and meiosis. Mitosis replicates and results in two identical daughter nuclei (genetically identical). Apart from these, they also act as adult stem cells which plays a major role in healing the damaged cells or repair the damaged cells. somatic cells are found all over your body except the germ cells.
Benefits of cell division in somatic cells:
- If you get hurt and eventually your blood will stop oozing out and get healed by the mitotic cell division found in the somatic regions of your body.
- Animals like lizards when get hurt, they get their cells automatically repaired by their somatic cells.
These are few important benefits other than the identical copies that are obtained by cell division.
D :D hope it was right I'm not sure but I'm trying so if it is ur welcome
