Answer:
The statement is FALSE.
Explanation:
In genetics, expressivity refers to the amount of variation in a non binary phenotype across individuals, who are carrying a specific genotype. Scientists believed that variable expressivity is controlled by different factors such as environment, genetics and lifestyle choice. An example of expressivity is a series of blue eye color that has different shades of blue. Thus, expressivity is not about balanced genetic output but varied genetic expression.
TSH level, because if we are testing the levels of TSH with a person who has Hashimoto's disease and one who does not have Hashimoto's disease.
The right answer is B.
The answer B is the only proposition which specified at which stage the event must occur, in fact, the meiosis.
Meiosis is a characteristic division of reproductive cells that can generate gametes to form new species (desendence). So if a mutation occurs at this time (such as recombinations) it will inevitably be inherited.
