Question

Why do bacteria only have one allele?

Answer 1

Bacteria only have one allele because:

1. An allele is a variant form of gene.
2. Bacteria are prokaryotes.
3. They may contain a plasmid, a little circular fragment of extrachromosomal DNA. Prokaryotes only have one chromosome, hence there is only one allele for each gene.
4. In every organism that reproduces sexually, each parent gives one allele for each of its genes, giving this offspring two alleles per gene.genes.
