What is the probability that a father produces a gamete with the allele for attached earlobes if he has one allele for detached earlobes and one allele for attached earlobes?
50%
What is a recessive allele?
Recessive allele is a trait that doesn't show in one's phenotype (observable trait) if there is a dominant allelle present. Only when you inherit a recessive allele from both parents (aa for example and not Aa) does the trait show in your phenotype.
What is the probability that a particular allele will be in a gamete?
chromosome segregationIf the character is governed by a single allele and it is dominant, than its probability to be in the gamete is 75%.
What is relative allele frequency?

What is the probability that each child born to two carriers of a recessive disorder allele will have the disorder?
The child will have the disorder, only if the recessive allele from both the parents is transferred to the child. Therefore, the probability is 1/4.
True or false Mutations are not capable of altering allele frequencies?
In the strict sense, no. Mutations happen to individuals and are only heritable in the germ line. Populations have allele frequencies in their gene pools. So, the mutation must be beneficial, lucky enough that it original carrier passes it on intact and that it is driven into the populations gene pool in sufficient number, by having reproductive success, to change allele frequencies.
Do mutations cause change in allele frequencies within a population?
Yes, they can. Mutation is one of the four main mechanisms of evolution.
Why are mutations are important for evolution?
Mutations serve up the variations in organisms to natural selection. The reproductively successful variations pass on these successful traits to progeny and allele frequencies change because of this and this is evolution.
What is the type of equilibrium that occurs when allele frequencies do not change?
Genetic equilibrium is when the allele frequencies remain constant.
What does it mean for a population to be in genetic equilibrium?
It is a situation where allele frequencies remain constant.
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.
Do Stable allele frequencies prevent microevolution?
no
How do mutations relate to variations within a population?
Essentially, they are what directly causes evolution. Evolution is the shifting of allele frequencies in a population. Variant alleles come into existence through reproductive shuffling, mutation. Natural selection is what then determines in what 'direction' the allele frequencies in the population gene pool shift, whether some variant allele spreads throughout the population, or fades from it.
When microevolution occurs what kind of frequencies change?
allele
How are alleles frequencies related to gene pools?
The frequency of the allele represents the percentage of that allele in the gene pool
What is the process called when allele frequencies in a population of a species change over time?
Evolution; the change in allele frequencies over time in a population of organisms.
Does natural selection on single-gene trait cannot lead to changes in allele frequencies?
Natural selection on a single-gene trait can lead to changes in allele frequencies for the alleles of that gene.
