Animals reach their carrying capacity when there is a lack in food and water supply to sustain the population. Therefore, the population cannot grow any further.
Answer:
The tasting allele is dominant.
Explanation:
- The law of dominance states that the dominant allele will always express itself in homozygous or heterozygous conditions.
- While, the recessive allele Can express itself only in Homozygous recessive condition.
- The phenotypic ratio in case of monohybrid cross is 3:1 where i.e , about 3 out of every four offspring tends to express the dominant trait.
- According to the given statistics,80% of the population can taste PTC and 20 % cannot.
- Thus The tasting allele is a dominant allele.
