Answer:
525 grams
Explanation:
Assuming the solution to be prepared is 15% by weight calcium chloride, it means 15 grams of calcium chloride will be in 100 mL of solution.
To calculate the amount needed to make 3500 mL solution;
15 g is required to make 100 mL
X g is required to make 3500 mL
X = 15 x 3500/100
= 525 g
<em>Therefore, 525 grams of calcium chloride will be needed to make 15%, 3500 mL of calcium chloride solution.</em>
The mother's genotype can be either
or
.
For X-linked recessive traits, males (XY) can either be affected or free from the disorder, they cannot be carriers. Females (XX), on the other hand, can be affected, unaffected, or be carriers.
The circled male child is free from the disorder (
) while the females are carriers (
).
The male inherited the healthy allele,
, from the mother.
The female children inherit the affected allele from their father (who is affected for the disorder) and the other healthy allele from their mother.
This means that the mother cannot be affected for the disease. As it is, the pedigree points that all the children got their healthy alleles from their mother. This does not mean the mother has two healthy alleles though.
Thus, the possible genotype of the mother are
and
.

Hey Leeann479!
The chart that shows all the possible combinations of alleles that can result from a genetic cross is called a
Punnett Square! I've attached an example of one to this answer.
Hope this helps!
