Question

If an allele makes up one fourth of a population's alleles for a given trait, its relative frequency is

Answer 1

.25

This is because 1/4 = .25

To find the allele frequency, you need to find the decimal representation of the fraction.

For example: If an allele makes up four twentieths of a population's alleles, then the frequency would be .2 (4/20 = .2)

Answer 2

An alternative form of genes that are variant and are responsible for conferring the phenotypic character is called an allele. A single allele gets inherited to the offspring from each parent. The allele can make purebred or heterozygous traits.

The relative frequency is 25%.

What is the relative frequency and how it is calculated?

A chance or probability of the occurrence of the gene carrying the specific allele in the percentage of a certain population is called relative frequency.

• The allele is the question that makes up the $\dfrac{1}{4} \rm th$ population hence,

$\begin{aligned} & = \dfrac{1 }{4} \\\\& = 0.25\end{aligned}$

• For calculating it in percentage:

$\begin{aligned} & =0.25 \times 100\\\\& = 25 \%\end{aligned}$

Therefore, 25% is the relative frequency.
