How might the presence of a chemical mutagen affect the genetic size of a population over time?
It affects the population because mutations can be deadly and they're passed down from one generation to the next making the population shrink.
What explains the presence of homozygous and heterozygous organisms within a population?
genetic divesity
How does genetic combination help a species to survive?
It causes diversity and variation amongst a population
What clues to the presence of certain genetic disorders can be seen in a karyotypes?
-Extra, missing or damaged chromosomes could show the presence of genetic disorders.
What is any non genetic influence?
Environment
Why genetic variation is a benefit to a population?
Genetic variation allows a population to adapt to a changing environment.

How does variation in a species help the species survive?
As each new generation is produced, genetic variation may be introduced into a population. The more genetic variation in a population, the more likely it is that some individuals might have traits that will be advantageous if the environment changes.
The chemical responsible for genetic information in a cell is?
The chemical responsible for genetic information in a cell is DNA
What would decrease genetic variation in a population?
When there is low genetic variation in a population the species produced are unlikely to withstand diseases.
What causes genetic diversion in nature?
effect of genetic diversion on environment
True or False When a population is in genetic equilibrium there is no genetic variation among individuals in that population?
True
What are the minimum structural metabolic and genetic equipment for a protobiont to be considered a true cell?
Simple reproduction, metabolism and excitability, maintenance of an internal chemical environment different from that of their surroundings.
What is one reason that cheetash are endangered?
Low genetic diversity is the most important factor for Cheetahs to adapt in the changing environment. Their population is dwindling, hence these are endangered.
