In a heterozygous allele
WebThe allele for haemophilia is recessive so two copies are needed for a female to have the disease However, because males only have one X chromosome, they only need one copy of the haemophilia allele to have the disease. This means haemophilia is much more common in males than in females. For example: Functioning allele = H Haemophilia allele = h WebJun 16, 2024 · When the loci in the matching chromosomes bear the same alleles, it is described as heterozygous. For example, a ‘heterozygous’ organism for a particular trait means that it possesses dissimilar alleles (e.g. Aa); one of the alleles is dominant and the other is recessive. The dominant allele, according to Mendel’s Law of Dominance, is the ...

WebMendel's Principle of Independent Assortment states that the alleles of each trait sort into gametes independently of each other. This means that a gamete will contain either a seed-color allele (A or a) or a seed-shape allele (B or b), but not both.
