Discontinuous characteristics are ____ in humans

Discontinuous characteristics are common in ______

What are some examples of discontinuous characteristics?

Why are these characteristics useful for geneticsists?

What is genetic diversity the basis for?

Why is a species with a high genetic diversity more likely to have more members that survive in a change in the environment?

Some populations have low genetic diversity due to natural or human causes. What are these 3 causes?

What is meant by a genetic bottleneck?

Why does this mean the genetic diversity is reduced in the smaller population?

Why will the genetic diversity gradually increase in the new population?

The vast majority or intraspecific variation is caused by what?

What is the name given to the technique that is useful for studying the causes of variation in humans?

What does this entail?

Why will the variation between the identical twins probably be due to environmental causes?

What is meant by the founder effect?

The few individuals will only have a small range of alleles between them so the founder effect is and example of what?

What does this mean about the new populations made in terms of genetic diversity?

What do these terms mean?

Selecting certain alleles and rejecting others during selective breeding means the genetic diversity of the animals or plants is _______

What is the purpose of selective breeding?

What does this result in?

Why are these new breeds sometimes recognised as new species?

Why are selectively breeding animals and plants not able to survive well in the wild and why are they highly susceptible to changes in the environment?

What can intense selection lead to in terms of domesticated animals?

Why wouldn't these fully develop in the wild?

What ethical argument does this arise?

All the organisms living in a habitat are collectively called its _________

What does interspecific diversity (or species diversity) mean?

Why is species diversity useful?

In order to measure species diversity we need to ____ ________

What is meant by the 'species richness' of a sample?

What does species richness not take into account which makes it less useful?

What is the calculation we use to measure the species richness and their abundance?

What is D?
