use that image, i hope this helps you. idk what type of biology it is sooo
If this is a true or false question the answer is true because they have so many people that they have trouble growing food and will eventually lead to major problems

Answer: The color of the iris is the example of polygenic inheritance.
Explanation:
Polygenic inheritance can be defined as the inheritance in which one trait is controlled by the two or more than two genes. The color of the skin, color of iris, weight and height are polygenic traits. The color of the iris is the polygenic trait the number of genes responsible for this are unknown but these genes are responsible for the synthesis of melanin pigment imparting color to the iris. OCA2 and HERC2 are the chief genes present on chromosome 15 responsible for this trait. Dark brown and black eyes are expected to have more amount of melanin as compared to the green and hazel eyes.
Mitotic division in onion root cells:
- Prophase: the emergence of chromatin threads that form chromosomes, the chromosomes are visible and overlap.
- Metaphase: chromosomes line up and line up in the middle of the equatorial plane. The centromere of the chromosome appears to have bonds with the kinetochores connected to the spindle threads.
- Anaphase: the centromere of the chromosome undergoes division then the chromosomes are pulled by the spindle threads towards the two opposite poles and leave the center of the equator that looks empty.
- Telophase: The cytoplasm divides into two identical-looking daughter cells. At the telophase stage, the process of cell division occurs in two parts and has identical properties.
Mitosis is a cell division through the stages of prophase, metaphase, anaphase, and telophase. The purpose of mitosis is for growth and regeneration which results in two daughter cells that are identical to the original parent cell. Mitosis occurs only once and lasts only during somatization.
