B is the allele for brown eyes & b is the allele for blue eyes. Two brothers both have brown eyes, but one of them has a B allele & b allele, while the other brother has only B alleles. Which statement is true?
They have the same genotype but not the same phenotype.
The genotype & phenotype are the same.
They have the same phenotype but not the same genotype.
Neither the phenotype nor genotype are the same.

Two identical alleles for a trait is known as
homozygous
heterozygous
mutation
codominance
A purebred horse with white hair is crossed with a purebred horse with brown hair. Each of their offspring has both white and brown hair. Why does this occur?
several alleles work together to determine a trait
two alleles for hair are dominant
two alleles for hair are recessive
the alleles for fur color are neither dominant or recessive
Factors that control traits are
purebreds
genes
recessives
parents
hidden allele
dominant allele
recessive allele
present allele
A gene is
a section of DNA
a chemical found in the nucleus of cells
contains instructions for building a protein
