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.

Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). The sympathetic nervous system (SNS) releases the hormones (catecholamines - epinephrine and norepinephrine) to accelerate the heart rate. The parasympathetic nervous system (PNS) releases the hormone acetylcholine to slow the heart rate. Such factors as stress, caffeine, and excitement may temporarily accelerate your heart rate, while meditating or taking slow, deep breaths may help to slow your heart rate.
