a dominant allele is an allele that takes over the recessive allele and a recessive allele is a trait that is skipped or held back

What are the two terms for having matching alleles for a certain trait?

The two terms for having matching alleles for a certain trait are "homozygous dominant" (two dominant alleles) and "homozygous recessive" (two recessive alleles).


How dominant and recessive alleles are represented in a Punnett Square?

Dominant alleles are written in upper case (i.e, 'A'), while recessive alleles are lower case (i.e, 'a')


How is recessive alleles different from dominant alleles?

You need two recessive alleles to get their trait, but only one dominant allele to get that trait. A dominant allele basically overrides a recessive one if they are together, but the recessive gene can show up in offspring.

How do dominant alleles recessive alleles differs?

Dominant alleles are the ones that show up in the phenotype. Recessive alleles do not unless both alleles are recessive, but can be passed on. For example: Tt , T=tall and t=short. Tall is dominant and short is recessive. You are tall and can pass on the short gene. Or, you can use black hair being dominant over red. Or, brown eyes being dominant over blue. Dominant can be seen on you and recessive can't.


Are organisms with alleles BB recessive or dominant?

Organisms with alleles BB are considered homozygous dominant. This means that the dominant allele (B) is expressed in the phenotype. Dominant alleles mask the effects of recessive alleles in heterozygous individuals.


What makes a dominant alleles different from a recessive alleles?

A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
