Sexual vs Asexual Reproduction
Bony fish reproduce by sexually because sperm and egg are developed in both males and females. Male and female mate and they have sex to fertilize an egg together, which will eventually become a baby. Females tend to produce more than 28,0000,000 eggs, which is why the population growth is so high. Some bony fish are either hermaphrodites or unisexual, which means one organism reproduces both sex cells and unisexual means there is no fusion of sex cells and can have fertilization.
Stages of Development .
Chromosomes- In Bony fish have a number of 18-104 chromosome pairs. Chromosomes in Bony fish support the evidence of evolution in bony fish because it is in the sub-divisions of the class of Osteichthyes. Division of the class is much more specific because it shows how fish are related to each other. Most species are closely related due to the similar number of chromosomes.
