Question

what is the meaning of allele​

Answer 1

Answer:

An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.

Explanation:

Each of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.

__________________________

• Variant of gene. Different allele can lead to different phenotypes.

• Diploids have two copies of each gene.

__________________________

Examples :-

• dominant purple allele
• the recessive white allele
• dominant tall allele
• recessive short allele
• dominant yellow allele
• recessive green allele.

___________________________

Three types of allele :-

$| {}^{A}$

$| {}^{B}$

$i$

The possible human phenotypes for blood group are type A, type B, type AB, and type O.

Allele Frequency :-

P = 11/16 = 0.6875

( i.e 2 × Homozygotes + Homozygotes )
