Question

based on the pictures below, indicate the process and include a brief definition. (mitosis, meiosis, sexual reproduction/fertilization, or crossing over)

Explanation:

• Top - left image: The process is Mitosis. Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
• Top - right image: The process is Sexual Reproduction/Fertilization. Fertilization is the union of a sperm and an egg cell, forming a zygote.
• Bottom - left image: The process is Crossing Over. Crossing over is the exchange of genetic material between non - sister chromatids of homologous chromosomes during meiosis, leading to genetic recombination.
• Bottom - right image: The process is Meiosis. Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four daughter cells (gametes in animals), each with half the number of chromosomes of the parent cell.

Answer:

• Top - left: Mitosis (a cell division for growth with same chromosome number in daughter cells)
• Top - right: Sexual Reproduction/Fertilization (sperm - egg union to form zygote)
• Bottom - left: Crossing Over (genetic material exchange in meiosis)
• Bottom - right: Meiosis (cell division halving chromosome number for gamete formation)
