Document Summary

Slide 7: gene influence physical and psychological makeup. Slide 9: chromosomes contain sequences of the genes, and 23 are each combined from the sperm and eggs, and determine the genes that are found in the offspring. Parents have a possibility of making 223 different children that have genetically different genes. This will ensure variability is formed among people. Mutation can also occur during meiosis (the fusion of the gametes), and add to the variability. Even when cockroaches are exterminated in an area, some survivors can procreate. The offspring will continue to thrive, and inherit the genetics, like the genes that allowed the parents to be immune to the pesticides. So when they repopulate, most will survive when you try to exterminate with the same pesticide. Equaluminant- the green and red colours give off the same light, so some people cannot perceive some of the colours. Another example: some people can taste the spiciness , which is genetically inherited.
