What does it mean for a population to be in genetic equilibrium?
A population is in genetic equilibrium when allele frequencies remain constant over generations, indicating that there is no evolution occurring. This suggests that the population is not experiencing any genetic drift, gene flow, mutations, or natural selection.
What does the word dominant mean in genetics?
In genetics, "dominant" refers to an allele that will be expressed in the phenotype if present, masking the expression of the corresponding recessive allele. This means that even if an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele's phenotype will be visible.
What does it mean if a trait or allele is resevive?
A recessive trait or allele is one that is only expressed when an individual has two copies of it, one inherited from each parent. In the presence of a dominant allele, the recessive allele's expression is masked.
What does the notation Rr mean to geneticists?
The notation Rr indicates that an individual has one dominant allele (R) and one recessive allele (r) for a specific gene. This is known as being heterozygous for that gene. The dominant allele will usually determine the individual's phenotype.
What does The presence of an allele for purple flowers will mask the presence of an allele for white flowers mean?
Gene responsible for purple color is dominant over white color.
When does fixation mean?
And human growthwhen does fixation mean
What does it mean for a population to be in genetic equilibrium?

What is an allie that is covered up or hidden?
If you mean allele, then the answer is a recessive allele. A recessive allele is dominated by a dominant allele, and generally does not show up physically.
What is meant by the allele frequency?
An allele frequency measures how common certain alleles are in the population. "The distribution of alleles in a population" -Apex
What is a type of gene?
Do you mean allele? An allele is a different molecular form of the same gene.
What does the term cystopexy mean?
Surgical fixation of the bladder.
What is allel frequency?
Allele frequency is the frequency at which a particular allele occurs in a population. For example, the genes for eye color involves many alleles: blue, brown, green, hazel. etc. Allele frequency refers to how often each expression shows up in a population, so for example in America the allele frequency for blue eyes may be 25%, hazel 15%, green 5% and brown 50%, with 5% left for other minor alleles. This would mean approximately 50% of the alleles for eye color in the American population are the "brown" variant.
What does the medical abbreviation CFT mean?
Complement-fixation Test
What does the term Oscar active fixation leads mean regarding radiology?
It should be Oscor active fixation leads. It refers to the leads of a pacemaker.
What does 'R' and 'r' mean in chromosomes?
R is a dominant allele for trait 'r' and r is a recessive allele for trait 'r'.
What does the term allele mean as is used in genetic crosses?
The term allele is different from a genotype because an allele can be singular, but the alleles that an individual (diploid organism) has at a certain locus are called a genotype.
What does evolution mean in sicence trem?
To be strictly genetic; evolution is the change in allele frequency over time in a population of organisms. Loosely; evolution is change over time in living organisms.
