Question

if an organism that phenotypically has dominant traits is mated to another organism that also has dominant traits, and the progeny have both dominant and recessive traits it indicates that ____________ multiple choice one parent is heterozygotic and one is homozygotic no conclusions can be made about the genotypes of the parents both parents are homozygotic both parents are heterozygotic

Explanation:

In genetics, for recessive traits to appear in offspring when both parents have dominant - phenotypes, both parents must carry the recessive allele. Heterozygous individuals have one dominant and one recessive allele. When two heterozygous individuals are crossed, according to Mendelian genetics, there is a chance for recessive traits to appear in the progeny. If one parent was homozygous dominant, only dominant - trait offspring would result. If both were homozygous dominant, all offspring would have dominant traits.

Answer:

D. both parents are heterozygotic
