WebDespite extensive morphological divergence, these species only diverged 10 kya and produce fertile hybrids in the laboratory. Out of 9.3 million genome-wide SNPs and 80,012 structural variants, we found very few alleles fixed between species—only 157 SNPs and 87 … WebIt depends on the gene. As an example, say you have a gene that makes an enzyme that catalyzes a necessary chemical conversion in the body. The enzyme 21-hydroxylase is a good example. If you have two alleles that both make a well-functioning 21-hydroxylase enzyme (you are homozygous dominant), you are good. lynch real estate basehor ks https://sportssai.com
