Allele frequency can change over time since natural selection and other
KonstantinChe [14]

These various variations of a gene are referred to as alleles. For instance, two alleles may occur at one specific locus, one of which codes for the cytosine base and the other for the thymine base. One copy of the human genome is inherited from each parent. We are hence referred to as diploid organisms.

<h3>What is Allele Frequency ?</h3>

The relative frequency of an allele at a certain locus in a population, represented as a fraction or percentage, is known as gene frequency or allele frequency. The percentage of chromosomes in the population that carry that allele relative to the whole population or sample size is what is being discussed.

The frequency of an allele in a population is referred to as its allele frequency. It is calculated by dividing the number of gene copies by the number of times the allele occurs in the population. All the copies of every gene in a population make up the gene pool of that population.

<h3>What is Allele ?</h3>

Leading textbooks on genetics and evolution define an allele as a different variation of the same sequence of nucleotides at the same location on a long DNA molecule. "The chromosomal or genomic location of a gene or any other genetic element is called a locus and alternative DNA sequences at a locus are called alleles.

How can recycling impact the environment? A) It uses less energy to make something from recycled materials than from new materia
o-na [289]

Answer:

A) It uses less energy to make something from recycled materials than from new materials.

Explanation:

When a recycled material is used to make a new product, it conserves energy because the recycled materials have already been processed once; so making something from it for the second time uses less energy-intensive than the first. For example: Making new aluminium from old products uses 95% less energy than making it from scratch.

Hence, the correct answer is "A)"
