Alleles can either be recessive or dominant. Dominant alleles produce a dominant trait which is normally seen, whereas although the recessive allele is present, the recessive trait is not normally visible. However, in cases of codominance and complete dominance the dominant trait does not completely hide the recessive trait and it can show through.
What else can I help you with?
Two different forms of the same gene are called?
Alleles
The different forms of a trait that a gene may have are called?
Alleles
Circle the letter of each sentence that is true about alleles. a. Recessive alleles are never present when dominant alleles are present. b. Alleles are different forms of a gene. . c. Dominant alleles?
The true statements about alleles are: b. Alleles are different forms of a gene. Recessive alleles can be present alongside dominant alleles; they are simply masked by the dominant ones. The statement about dominant alleles is incomplete, so it cannot be evaluated as true or false.

When both alleles contribute to the phenotype of a heterozygous the alleles are said to show the dominate alleles and sometimes the recessive but mostly the dominate alleles
