Alternate forms of a gene

●An allele is an alternative form of a gene that is located at a specific position on a specific chromosomes.
●While, homologous chromosomes are made up of chromosome pairs of approximately the same length, centromere position, and staining pattern, for genes with the same corresponding loci.
●An allosome is a chromosome that differs from an ordinary autosome in form, size, and behavior. The human sex chromosomes, a typical pair of mammal allosomes, determine the sex of an individual .
