Strange creatures have 7 genders

When protozoan Tetrahymena thermophila mate, there are 7 types of sex-matched genes, so the gender of the next generation will be different from their parents, Tetrahymena 'descendants' can have up to 7 genders.

Tetrahymena thermophila, bizarre creature has 7 genders

Scientists have discovered the complex characteristic of determining the afterlife of this bizarre creature, the subsequent sexual formation of this creature is completely randomized.

This new study has been published in the March 26 issue of the "Science and Biology Library" . Tetrahymena is a cell with two nuclei: a small nucleus containing the necessary material for reproduction, and a multiplication of a machine chamber creates flexibility for this organism. The multiplication of Tetrahymena thermophila contains at least 25,000 genes, nearly equal to the human genome and is divided into about 200 chromosomes.

Each Tetrahymena has its own gender or its own mating model - existing in the cell wall. When this bizarre organism interacts, there are seven sex-regulated pairing genes, the paired genes will go through the final selection process to retain only one standard gene, the other six will be eliminated. . The modified DNA becomes part of the next cell of Tetrahymena and will determine their sex. Because there are 7 types of paired sex genes, this bizarre creature has 7 genders.

This finding has helped scientists understand more about other cells including cells in the human body.
