Oncogenes are most like the gas pedal on a car, while tumor suppressor genes are most like the brakes on a car. Oncogenes and tumor suppressor genes are mutated in cancer cells.

Oncogenes are genes overexpressed in cells in which they should not be expressed, thereby leading to cancer.

Some examples of oncogenes are growth factors such as, for example, the  Platelet-derived growth factor (PDGF) or Epidermal growth factor (EGF).

Conversely, tumor suppressor genes are genes that act to regulate cell division and replication, thereby their inactivation also leads to cancer.

A well-known example of a tumor suppressor gene is the p53 gene that acts to control cell division and apoptosis (programmed cell death).

Modern humans arose in Africa at least 250,000 to 300,000 years ago, fossils and DNA are the evidence that  reveals. Scientists have been unable to pinpoint a more specific homeland because the earliest Homo sapiens fossils are found all across Africa.

Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Most scientists currently recognize some 15 to 20 different species of early humans found from Africa.

F. genotype

G. Punnet square

H. nondisjunction

I. mitosis

J. sex cells

Explanation:

In meiosis cell division, a parent cell divides into four daughter cells whereas in mitosis, one cell divides into two daughter cells. If change occur in DNA molecules, mutation occurs. Phenotype refers to physical characteristics of an organism whereas genotype indicates genetic characteristics. Recessive traits only appears when the organisms have same traits or allele. Somatic cells is known as body cells whereas gametes is known as sex cells.
