Is an organism produced from two different species or genotype. Hybrid: female horse+male donkey =mule, female donkey +male horse = hinny, such hybrids, however are usually incapable of reproducing themselves. 1: are three like structures found in the nuclear of most cells. They contain the genes determine sex are normally are constant in number among species: a picture of chromosomes is called a kayeotype.
