The probability of the female child of Charles and Marie suffering from hemophilia is 50% or 0.5.
<h3>What is the probability of hemophilia?</h3>
Hemophilia is a disease that is linked to the X-chromosome.
The probability of having female who suffers from hemophilia depends on the genotype of the parents.
Assuming that the genotype of the parents are as follows:
Father: XcY --> hemophilic
Mother: XXc --> carrier
A cross between the parents will produce two female offspring with genotypes, XcXc and XXc.
Therefore, the probability of the female child of Charles and Marie suffering from hemophilia is 50% or 0.5.

Answer:
The word "precocious" means gifted.
The BRCA 1 and BRCA 2 genes are two genes that are sought in the genetic study of an individual in order to seek a predisposition to breast cancer (in women and also in men).
The genes of Tay-sachs, are researched in order to diagnose or eliminate Tay-sachs disease.
The first difference lies in the goal of the research: for the BRCA (screening) genes, a predisposition is sought and for the Tay-sachs genes, it is sought to confirm the disease.
The second lies in the technique used:
The first step in the study of these genes is to isolate and replicate them. The best technique for this is the PCR (polymerase chain reaction). By using primers we can amplify the gene we want. So the primers used in BRCA and Tay-Sachs research are necessarily different.
The correct answer is 3- <span>The smelt and alewife may out-compete the native fish by consuming all of the zooplankton.
The diagram tells us that zooplankton is eaten by smelts and alewifes. If these two species increase in number, less of the zooplankton will be left for plankton-eating fish, which is a native type of fish, to eat.
</span>
<span> smelt and alewife eat most of the existing plankton so, they are out-competing the native fish.</span>
