WebWhat is a gene? Gene is a basic unit of hereditary that transfers some traits from parents to offspring. Genes are made up of specific DNA sequences and perform different roles in DNA replication, hereditary and genotype expression. What are alleles? The alternating forms of genes occupying a locus on chromosomes are called alleles. WebSummary. The Human Genome Project was a collaborative effort where scientists uncovered all the genes in the human genome. This was a hugely ambitious project given the state of technologies at the time.
