And remember, NEVER put petroleum-or mineral oil-based products on a sunburn. Because they form a seal, they'll lock in the heat into your skin, making the burn worse, not better. It could even lead to permanent scarring. Petroleum-based products form a seal on your skin...
Homozygous (or Purebred) - The genotype for the characteristic has the same genes/alleles (e.g. BB, bb). Heterozygous (or Hybrid) - The genotype for the characteristic has different genes/alleles (e.g. Bb). Wild-type - The most common phenotypes in a population are called the wild-type.
These multiple alleles are passed from parent to offspring such that one allele is inherited from each parent. There are six possible genotypes (genetic makeup of inherited alleles) and four phenotypes (expressed physical trait) for human ABO blood types. The A and B alleles are dominant to the O allele.When both inherited alleles are O, the genotpye is homozygous recessive and the blood type is O. When one of the inherited alleles is A and the other is B, the genotype is heterozygous and the blood type is AB.hese multiple alleles are passed from parent to offspring such that one allele is inherited from each parent.
