Answer AND Explanation:

<u>FACTORS THAT CAUSE GENETIC VARIATIONS</u>

  1. Crossing over. At the chiasmata during prophase I of meiosis, breakage may occur and exchange of genetic information may take place. New gene combinations which result in variations.
  2. Independent assortment. The arrangement of homologous chromosomes at the equator of the spindle during metaphase of the first meiotic division is random. These homologous chromosomes segregate into different daughter cells which contain different genetic combinations which brings about variation
  3. Fertilisation permits parental genes to be brought together in different combinations. This is the cause of variations in members of the same family.
  4. Mutation is the spontaneous change in the genetic makeup of an organism. These changes may be inherited by the offspring therefore beginning variation.

Explain how a single fertilised egg cell can devolop into billions of different cells in a human adult
Alex

Answer:

A fertilized egg cell is a single cell that can develop into one or more specific types of cells in the body. These cells include neurons, blood cells, skin cells, muscle cells, and many others. This process involves two major steps: differentiation and specialization.

During differentiation, each of the many types of cells in the body has to be developed separately. For example, skin cells have to differentiate into hair follicles, sweat glands, sebaceous glands, and so on. The developing brain cells must differentiate into a specific set of brain cells (neurons) that make up the cerebral cortex. During specialization, each of these specialized cells becomes specialized for its specific function. For example, skin cells specialize to form keratinocytes, which form the outer layer of our skin. Neurons specialize to make connections with other neurons in the brain. Blood cells specialize to carry oxygen throughout the body.

The process of differentiation and specialization is continuous, as new cells are constantly being created and old ones are constantly dying off. This continuous process of change is what allows the body to grow and develop throughout life.
