Multiple Alleles – Principles of Biology

WebIn nature, such genes often exist in several different forms and are therefore said to have multiple alleles. An individual usually has only two copies of each gene, but many different alleles are often found within a population. A rabbit's coat color is determined by a single gene that has at least four different alleles. WebMar 22, 2024 · Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases. WebApr 12, 2024 · The relatively short restoration time probably contributed to the lower genetic diversity in the restored populations compared to the reference populations. Studies have shown that degraded populations may need more than 100 years to recover biodiversity to the level of reference populations (Rozendaal et al. 2024).
