Freckles are a dominant trait in humans. both of the girls have the genotype ff for freckles. if either one marries a man with no freckles, what are the chances that their children will have freckles? a) 0% b) 50% c) 75% d) 100%

The correct answer is option D, 100 %

Explanation:

Freckles are a dominant trait in humans

The female partner has genotype = FF

The male partner with no freckles shall have genotype = ff

The cross between the above two is represented through a punnet square-  

FF

f FfFf

f FfFf

Thus all the offspring will have genotype Ff,  

Since the dominant allele is F . thus all the offspring would have freckles

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
