Answer:
A. Incomplete dominance.
Explanation:
Incomplete dominance is the ability of two alleles to produce a heterozygous phenotype different from the two homozygous phenotypes.
Example is when a pure stock of red flowered (RR) four o'clock plant is been crossed with a white flowered(rr) one, the offspring are all pink flowered(Rr), showing a blending of flower colour character. Self pollination of the pink flowered F1 individual produce a mixture of F2 individual bearing red, pink and white flowers in the ratio of 1:2:1. This reappearance of the red flowered and white flowered forms in the F2 generation shows that alleles R and r have remained unaltered in the F1 generation.

"Which three components are common to all amino acids? The key elements of an amino acid are carbon (C), hydrogen (H), oxygen (O), and nitrogen (N), although other elements are found in the side chains of certain amino acids."
Answer:
Oswald Avery, Colin MacLeod, and Maclyn McCarty showed that DNA (not proteins) can transform the properties of cells, clarifying the chemical nature of genes. Avery, MacLeod and McCarty identified DNA as the "transforming principle" while studying Streptococcus pneumoniae, bacteria that can cause pneumonia.
