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.

Explanation:
There are two compositions in blood.
1. Plasma (55%)
2. Blood cells (45%)
Again Blood cells is divided into:
RBC ( Red blood cell)
It transports oxygen for respiration.
WBC ( White blood cell):
They help in the formation of antibodies to fight against germs and bacteria.
Platelets:
It plays major role in healing of the wounds.
To test the Porosity of the hair, one should select a small section of hair at the crown, hold it at the root and the tip, and slide the hair down two to three times slowly. The porosity of the hair is the ability to absorb moisture and may be low, normal or high. A porosity test indicates the category of an individuals hair. It is important since one is able to maintain hair's health than merely just knowing the hair type.
Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. ... While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration
