Which of the following statements about dominant traits is correct? a) they are observed three-fourths as frequently as heterozygous traits. b) the dominant trait is typically masked by the recessive trait. c) they are observed less frequently than recessive traits. d) they increase in frequency over evolutionary time. e) the dominant trait is the one which is expressed.

Option E

Explanation:

A dominant trait is the characteristics associated with an allele which is expressed even if only one dominant allele is present in any allele pair.  

For example - Let us say that “R” represents the allele for red colour and “r” represents the allele for white allele.

Also, red colour allele is dominant over white colour allele.  

Thus in an allele pair “Rr” the colour expressed would be red as it is a dominant trait.  

The white colour alleles in an allele pair would be expressed only when both the alleles are recessive.  

Hence, option E is correct

it would affect precipitation by causing flooding in some areas of the world due to climate increasing, causing the glaciers in the northern and southern pole of our planet to melt.

i wish you would have provided choices to simplify it and allow me to give an exact answer.
