Question: Explain selective breeding in your own words.
Answer: Selective breeding is a process of breeding animals or plants with desirable traits in order to produce offspring with those same traits.
Question: Explain natural selection in your own words.
Answer: Natural selection is the process by which certain traits become more common in a population over time.
Question: Some male peacocks used to have bright and large tails while others had dull, smaller tails.Female peacocks will only mate with the ones that have the brightest and largest tails. Explain how this would impact the offspring of male peacocks over time.
Answer: Over time, the offspring of male peacocks with bright and large tails would become increasingly more common in the population. This is because female peacocks will only mate with males that have the brightest and largest tails, meaning that the genes for bright and large tails will be passed on to the offspring more often than the genes for dull and small tails. As a result, the population of peacocks will become increasingly more likely to have bright and large tails.
The breeding of animals is necessary to produce OFFSPRING.
Humans have bred animals and plants for years through the process of SELECTIVE BREEDING in order to hand-select traits needed in the livestock or produce.
In nature, it is not quite so simple. Charles Darwin was a naturalist that proposed the idea of NATURAL SELECTION.
When visiting the Galapagos islands, he discovered there was great DIVERSITY between the tortoises on different islands.
The different tortoises had specific ADAPTIONS to survive on the islands that they were found on.
