The gene responsible for thalassemia is carried on an autosome.

One key morphological adaptation of a cactus to prevent transpiration is its spines, which are modified leaves.

Cryopreservation is a method used to preserve biological materials like embryos, meristematic tissue, and seeds at very low temperatures, typically in liquid nitrogen.

GTH (Gonadotropin) plays two important roles in the secretion of hormones from the reproductive glands in the human body:

1. Stimulation: GTH stimulates the production and secretion of hormones from the reproductive glands, such as the ovaries in females and the testes in males.
2. Feedback Regulation: GTH also provides feedback regulation to maintain hormonal balance.

Central Nervous System (CNS):

• Brain
• Spinal cord

Peripheral Nervous System (PNS):

• Cranial nerves
• Spinal nerves
• Ganglia

The two importance of the cell cycle:

1. Growth and development: The cell cycle allows for the growth and development of organisms by allowing cells to divide and create new cells.
2. Repair and maintenance: The cell cycle also allows for the repair and maintenance of organisms by allowing cells to divide and replace damaged or dead cells.

In the experiment of hybridization dominant trait is expressed in F₁ generation and the recessive trait is suppressed. Example - In the cross between pure Black Male (B.B.) and pure white female (bb), all the guinea pig in F₁  generation are phenotypically black because blackness is the dominant character. In F₁ generation black and white both types of guineapigs are produced.

In incomplete dominance, the phenotypic ratio of the F2 generation is 1:2:1, the same as the genotypic ratio.
