How do the chromosomes of chickens contribute to their genetic makeup and overall development?

The chromosomes of chickens contain genes that determine their traits and characteristics. These genes play a crucial role in the development of chickens, influencing their physical appearance, behavior, and overall health. By carrying genetic information, chromosomes contribute to the unique genetic makeup of each chicken, shaping its growth and development from embryo to adulthood.


What factors determine an individual's biological sex, excluding the role of sex chromosomes?
