The correct answer is: Heartburn often results when the gastroesophageal sphincter fails to close properly.
The gastroesophageal sphincter is a muscle located at the bottom of the esophagus that has to be relaxed in order to allow food to flow down into the stomach. After it contracts (tightens), the food and the stomach acid can’t flow back up into the esophagus.
When the gastroesophageal sphincter fails to close properly acid reflux occurs and causes the heartburn.
Answer:
Heterozygosity
Explanation:
The correct term that could explain the phenomenon is heterozygosity.
<u>In heterozygous condition, a gene is made up of two different alleles in which one would be dominant and the other would be recessive. </u>
<em>In heterozygous purple plants in which the alternate color is white, the white color is not expressed because its allele is in a recessive state. If two heterozygous plants are mated, the recessive allele in each plant would combine into some of the offspring, resulting in the production of white color progeny in addition to the dominant purple color progeny.</em>
Let us assume that the purple color allele is P and the white color is p.
Pp x Pp
PP Pp Pp pp
PP and Pp - purple color
pp - white color.
Hello there,

I hope this helps you!
