A dominant allele is ________?

Question

a. a trait that is hidden by another trait

b. a trait that prevents the showing of other traits

c. a trait that has been altered by a DNA mutation

d. a trait that will not be seen in the next generation of offspring

Answer 1

b. a trait that prevents the showing of other traits

recessive alleles are masked by dominant ones. If an organism has a recessive allele and a dominant allele, the dominant one will be shown

Answer 2

a

Answer 3

BBBBBB

Answer 4

B

The answer is B because the dominant allele is "dominant" over the recessive allele. In other words, if both the dominant and recessive are present (ex: Bb) then only the B allele would be expressed. for example the dominant allele B represents thick hair and the recessive allele b represents balding. If you had the genotypes Bb or BB then you would have think hair because the dominant allele hides the recessive one so that only it is expressed (expressed meaning you have thick hair). But if you had the genotype bb, you would be balding.

Answer 5

B.
