A population in which allele frequencies do not change from generation to generation is said to be in?
A population in which the allele frequencies do not change from one generation to the next is said to be in equilibrium.
What would cause allele frequencies to remain unchanged?
Only one thing: extinction.
What does the hardy Weinberg principle state?
allele frequencies in a population will remain constant unless one or more factors cause those frequencies to change
Are Recessive traits always shown in an organism's offspring?
No, a recessive trait will only show in the offspring if there is no dominant allele masking it. The trait that will always show in the offspring is the dominant allele, provided one parent was homozygous for it.

Why don't gene frequencies change from one generation to the next?
the DNA remains the same. just different parts of it get translated
Do mutations cause change in allele frequencies within a population?
Yes, they can. Mutation is one of the four main mechanisms of evolution.
A flood kills most of the ants that live near a river. After the flood one population of ants grows rapidly but its allele frequencies are different from the frequencies before the flood. What does th?
Bottleneck
If and individual has one dominant allele and one recessive allele will the recessive allele show up?
YES ALWAYS!!! Even if you have for example, Aa (A being the dominant allele and a being the recessive allele) that trait will always be dominant!
How can micro evolution happen?
By simple genetic recombination for one. microevolution is just evolution and evolution is the change in allele frequency over time in a population of organisms. Just change over time short of speciation and especially valid for sexually reproducing organisms who always change allele frequencies through coitus and reproduction.
Is it true that if neither parent possesses a functional allele a child will always have PKU?
True you need at least one functional allele
When you add one cream allele to the basic bay coloring what color results?
Buckskin
What does dominate mean in DNA?
A dominant allele is one that will always be expressed when present.
Allele frequencies in a population tend to remain the same from generation to generation unless acted on by outside influences?
Genetic equilibrium is a theoretical concept used to study the dymamics of single alleles in the population gene pool. In practice, there is no situation in which allele frequencies do not drift to some degree. Large populations may slow drift down, but there will still be drift.
