What is meant by alleles?
Allele frequency, or gene frequency, is the proportion of a particular allele (variant of a gene) among all allele copies being considered. It can be formally defined as the percentage of all alleles at a given locus in a population gene pool represented by a particular allele.
What is a fact for homozygous?
an individual containing 2 copies of the same allele for a particular trait located at similar positions on paired chromosomes
How is a recessive allele from a dominant allele?
its different because adominant allele is in charge
What does it mean that CF is a recessive gene?
The phenotype associated with a recessive gene is only expressed when two copies of the gene are present. For example, if a person has both a recessive allele and a dominant allele for CF, the person does not have CF. The person only has CF if he/she has two copies of the recessive allele.
What type allele must have two copies for it to be expressed?
A diploid DER DA DER
What is meant by allele frequence?
How often a certain allele (or trait) occurs in a certain population.

How do you use comparison in a sentence?
There is no comparison between a student who does his own work and one who just copies what someone else does.
What is genotype AA?
Genotype AA refers to an individual who has two copies of the A allele for a particular gene. In genetics, genotypes are the specific combination of alleles an organism carries for a particular trait. In this case, the individual would express the trait associated with the A allele.
What term describes an individual with two copies of the same allele?
The individual with two of the same allele is "homozygous" for a trait.
Describe the relationship between dominant and recessive trait forms?
The relationship between Dominant and recessive trait forms is simple a dominant trait is an allele that hides or masks another allele. While a recessive trait is the allele that is hidden or masked by another allele such as the dominant trait, the recessive trait is ONLY expressed when two copies of the recessive allele are present.
How is a recessive allele from a dominant allele?
its different because adominant allele is in charge
A trait that requires two copies of an allele?
recessive
What does it mean that CF is a recessive gene?
The phenotype associated with a recessive gene is only expressed when two copies of the gene are present. For example, if a person has both a recessive allele and a dominant allele for CF, the person does not have CF. The person only has CF if he/she has two copies of the recessive allele.
For a gene with its locus on the X chromosome what term do you use to describe a male that only has one copy of this gene?
Hemizygous - has 1/1 copy of the allele Heterozygous - has 1/2 copies of the alleleHomozygous - has 2/2 copies of the allele
Is an allele that produces a trait in the heterozygous condition recessive?
No. A recessive allele will not be expressed phenotypically in the heterozygous state. A recessive allele can only be expressed phenotypically in the homozygous state.
