He discovers that mice that are exposed to high levels of UV radiation are much more likely to acquire cancer than mice that are not exposed to UV radiation.

2009-11-13 · Im not fully sure what you mean but genetic diversity comes around when the gametes are produced by the process of meiosis, this is where a cell is produced with half the number of chromosomes (a normal human has 46 chromosomes thus in these sex cells a sperm or egg will have 23) now these 23 chromosomes can be of any different combinations of the genes from their parents and thus causing
The greatest source of genetic diversity in sexual reproduction is the contribution of chromosomes from two different parents. Crossing-over also helps with genetic diversity by switching pieces of each homologous pair during … Sexual reproduction in Paramecium occurs only when environmental conditions deteriorate. Sexual reproduction involves the exchange of genetic material via cytoplasmic bridges during conjugation (Figure 2.18).It is a relatively complex process: two paramecia join laterally to form a cytoplasmic bridge. Variations in Sexual Reproduction: Types and Significance!

Sexual reproduction occurs in a variety of ways in animals. In some species, such as fish, the male releases sperm over the eggs after the female has laid them. In other species, such as birds and most mammals—including human beings—the male releases sperm into the female reproductive tract. This hypothesis fits well with the observation that a shift from asexual to sexual reproduction is initiated in many species upon exposure to environmental challenges (Ram and Hadany 2016). However, a “sex as diversity generator” hypothesis might be less compelling when one considers self-fertilization. During meiosis, cells are split so We get that genetic information from our parents through sexual reproduction.

When we look at it from the perspective of an ecosystem, we will see that it refers to the different species or ecological niches present. We can bring about genetic diversity in ecosystems by scaling things up within an area.
