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.
Best Answer: An allele is a DNA sequence that codes for a gene. In simpler terms, it is a given form for a gene. Two alleles for the same gene might be two alleles for blood type: A (for blood type A) and B (for blood type B).Humans receive two alleles for each gene: one from the mother and one from the father.est Answer: An allele is a DNA sequence that codes for a gene.
