Somebody needs at least one XC to not be colorblind. XcY doesn't have XC, so they are colorblind. XcXC has XC, so they are not colorblind. (a colorblind female would need both to be colorblind - XcXc)
And XcXC female can pass colorblindless onto her children. For example, even if the father was a normal male (XCY), the one possible child could be XcY (with Xc from the mother and Y from the father), which doesn't have XC so its colorblind.
Answer:
I believe that the answer to this question is B: It is unchanged in the experiment.
Explanation:
<span>Before the completion of the Human Genome Project, it took few years before the well-known forecasts stated that humans had at least 100,000 genes. But latest Human Genome Project evaluates lowered number to a more timid range of 20,000 to 25,000. It has helped to narrow the range of feasible genes and to separate certain candidates as supplying to particular diseases. Scientists have also re-evaluated past conclusions, such as the idea that genes are self-restrained, detached pieces of DNA with defined character. They now know that some genes that tasks simultaneously can make more than one protein; where in fact the average gene might make three proteins. Also, genes will be visible to grab genetic code from other DNA parts</span>
