The secret of evolution in papaya chromosomes
Text created by automatic translator Elia and has not been subsequently revised by translators. Elia Elhuyar
The papaya plant, Carica papaya, discovers that it can help explain the evolution of sexual chromosomes.
This plant is really unique, as it has flowers of three sexes: females, males and hermaphrodites. The Y chromosome of acidic and hermaphroditic flowers is similar to the X chromosome, but with fewer genes. The genes that determine sex are only 10%.
Researchers believe that the papaya Y chromosome is the precursor of the animal Y chromosome. And it seems that this study is also the starting point to show that sexual chromosomes developed from autosomes, not sexual chromosomes.
