Answer:

Usually the Y chromosome. It is recessive because if one Y chromosone is mutated with red-green colorblindness and the X is not, the child will have colorblindness. But, if one X chromosome has the mutation and the other X does not, they will cancel out, meaning the child will not have colorblindness.

Two positive integers are 3 units apart on a number line. Their product is 108.
Svetlanka [38]
The first integer as given in the question = m
Then
The second integer as described in the question = m + 3
Then the equation will be
m(m + 3) = 108
The correct option is option "A".
Now let us solve for "m"
m^2 + 3m - 108 = 0
m^2 + 12m - 9m - 108 = 0
m(m + 12) - 9(m + 12) = 0
(m + 12)(m - 9) =0
So the value of "m" is -12 and 9.

in dogs there is a hereditary type of deafness caused by a recessive gene. Two dogs who carry the gene for deafness but have normal hearing are mated. what are the possible genotypes and phenotypes of their offspring and the percent of chance for each?

Dd x Dd = DD, Dd, Dd, and dd

3:1 genotype

phenotype shows that there is 3 dominant gene for normal hearing while 1 for deafness (two homozygous where 1 is dominant and the other is recessive) and (two heterozygous with normal hearing dominant over deafness recessive)

Earth's tilted axis affects the strength of sunlight in different places on earth's surface. If you are in an area that is recei
levacccp [35]

The answer is; D


The angle at which the sun rays strike the earth at the equator is more or less 90 degrees while you move towards the poles, it much less than this. This means that the unit of sunlight per surface area received at the equator is higher than that at the poles. This is why the equator is always warmer than the poles.
