An allele is one of two, or more, versions of the same gene at the same place on a chromosome. It can also refer to different sequence variations for several-hundred base-pair or more region of the genome that codes for a protein. Alleles can come in different extremes of size.
Can gene copies be on different chromosomes?
Duplicated genes are linked by different colored lines depending on the chromosomes that the duplicates reside on. Only inter-chromosome duplicates are shown. Genes present on the Ax2 duplication, genes on the chromosome 5 duplication present in many Ax3 lines, and legends for Figures S1, S2 and S3.
Where do your alleles come from?
One allele for every gene in an organism is inherited from each of that organism’s parents. In some cases, both parents provide the same allele of a given gene, and the offspring is referred to as homozygous (“homo” meaning “same”) for that allele.
Who is known as the father of genetics?
Gregor Mendel. Gregor Mendel’s work in pea led to our understanding of the foundational principles of inheritance. The Father of Genetics. Like many great artists, the work of Gregor Mendel was not appreciated until after his death.
