Everyone (with a normal set) has 23 pairs of chromosomes. That’s 46 total chromosomes. You get an allele for each gene on each of the pair of chromosomes.

WebAlleles of a gene Since diploid organisms have two copies of each chromosome, they have two of each gene. Since genes come in more than one version, an organism can have two of the same alleles of a gene, or two different alleles. This is important because alleles can be dominant, recessive, or codominant to each other. WebRisk alleles could include (1) a heterozygous variant in a recessive NS gene that would be sufficient to cause Mendelian NS if found homozygously or in compound heterozygosity with a causal allele in trans for the same gene, or (2) a heterozygous variant in a dominant NS gene which is insufficient alone to cause NS alone based on a stringent ...
