In what way do two alleles for the same trait differ?

Explanation: Two alleles of a trait exhibit dominant-recessive behavior. The allele that can express itself in both homozygous and heterozygous condition is called "dominant" allele. On the other hand, the allele which is expressed only in homozygous genotype is termed as a recessive allele

Out of the two alleles of the same trait one may be dominant while the other is recessive. The dominant allele is always exhibited in the next progeny(generation)
