Darwin called the ability of an organism to survive and reproduce in its environment fitness.
Some organisms were fit to do all of these things, whereas others were not.

Fossil fuels specifically natural gas
Explanation:
The probability that a homozygous recessive individual would be producing a dominant allele would be 0%. If expressed as a percentage, this is because the individual does not even have the possible allele in its genotype for whatever trait or feature that the protein codes for.
Answer:
Explanation:
Prokaryotes, like most living organisms, need movement to locate food and to survive. If a prokaryote needed to move to a new food source, which structure would it use for locomotion?
Answer:
- If they have one child, the probability that he or she will be affected is 1/4.
- If they have two children, the probability that at least one of them will be affected is 7/16.
Explanation:
A cross between two heterozygous Aa individuals will produce the followinf offspring: 1/4 AA, 2/4 Aa and 1/4 aa.
Since the disease is recessive, 1/4 of the offspring will have the <em>aa </em>genotype and 3/4 of the offspring will be unaffected.
Every time they have children new gametes were generated <u>independently</u>.
The probability of having <u>no</u> affected children both times is, according to rules of probability for independent events, 3/4 × 3/4 = 9/16 (it's the probability of having a healthy child the first time multiplied by the probability of having a healthy child the second time).
The probability of having at least one affected child is 1 - probability of no affected children = 1 - 9/16 = 7/16.
