5c. Two parents, a heterozygous normal female and a male who is
Romashka-Z-Leto [24]

Answer and Explanation:

We can assume that being colorblind is a recessive trait.

That means the father has a genotype of both lowercase letters, denoted as bb.

Let's make a chart.

- The Father's Genotype is bb

- The Mother's Genotype is Bb (Because she is heterozygous, which means she has one Dominant trait (B) and one recessive trait (r))

<u>      b               b   </u>

<u>B|   Bb   |   Bb     |</u>

<u>b|   bb    |   bb     |</u>

We get 50% of the offspring to be colorblind, and 50% of the offspring to have normal color vision.

<u>That means the expected percentage is 50%.</u>

(Don't look too much into the capitalized MALE, its just there to throw you off guard and mess you up)

You feed a canned dog food that is 75% moisture. When analyzed, it contained 30% crude protein and 1.20% calcium on a dry matter
SVETLANKA909090 [29]
To solve the problem, let us note that the calcium percentage no longer considers the moisture content of the canned dog food. Taking the 75% of the sample 681 grams results in a moisture content of 510.75. This is "removed" from consideration and we're left with 170.25 grams which we multiply with the given (dry basis) percentage of calcium to get 2.043 grams of Calcium.
