How many alleles does a gamete have
WebIf our gametes had more than one allele for each gene, then the resulting zygote from the fertilization of two gametes would have more than 2 alleles for each gene and would have more than two homologous pairs of chromosomes. Of course some species do have more than two sets of chromosomes. This is known as aneuploidy. WebThat is, when the genes go into gametes, the allele received for one gene doesn't affect the allele received for the other. In a double heterozygous organism ( AaBb ), this results in the formation of all 4 4 possible types of gametes with equal, or 25\% 25%, frequency. Why …

WebAug 22, 2014 · It is estimated that humans have about 20,000-30,000 genes - meaning each gamete would therefore have 20,000-30,000 alleles. WebA gamete has a single set of genes - that means, that for each gene* it has only one allele. Thus, when two gametes combine to form a zygote, they create a diploid genome, in which each gene is represented by two alleles, one on maternal chromosome, one …
