Is albinism a recessive trait or dominant?
Recessive. The trait will only show up if both parents have the gene recessively (aa). If the genetic make up is Aa or AA, there will be melanin production, meaning albinism is an aa gene only. Albinism is a recessive allele.
What combination of alleles could produce a trait controlled by a recessive allele?
recessive + recessive or tt

Are smile dimples controlled by a recessive allele?
Nope, the alleles for smile dimples are actually dominant, not recessive.
How can albinism in plants keep occurring if they cannot reproduce?
because the recessive allele is still present in heterozygous individuals. these individuals have one dominant allele and so show the dominant phenotype but they are capable of producing offspring with the recessive condition
What is allele masked by the dominant allele?
An allele that is masked by the dominant allele is called a recessive allele. When an individual has one dominant allele and one recessive allele, only the trait determined by the dominant allele will be expressed. The recessive allele will only be expressed if an individual has two copies of it (homozygous recessive).
