Gregor Mendel developed several hypotheses about inheritance from his research on pea plants. Which of the following is not one of Mendel's hypotheses? If present, the dominant allele will determine the organism's appearance.
Genes are made of DNA.
Gametes carry only one allele for each trait.
Organisms inherit two alleles, one from each parent.

Gametes carry only one allele for each trait.

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
