Question

how many alleles does each parent contribute to their offspring for each gene?
three
four
two
one

In genetics, during sexual reproduction, each parent contributes one allele for each gene to their offspring. This is due to the formation of gametes through meiosis, where the chromosome - number is halved and only one of the two alleles present in the parent's somatic cells for a particular gene is passed on.
