In this Josephine is correct. While red will most commonly occur, if the 'r' is there then under Mendel's rules, a 3 to 1 ratio will appear. Ie for ever 3 red flowers, one flower will be the other colour.
Answer:
The correct answer is C
Explanation:
A plant consumes all the oxygen photosynthesis generates. It also uses all the carbon dioxide respiration creates. As a result, no gas exchange takes place with the environment. Bright sunlight – Photosynthesis uses carbon dioxide and makes oxygen faster than respiration produces carbon dioxide and consumes oxygen

Answer:
<h2>
Alice's daughter Alix =X X* </h2><h2>
George V= XY
</h2><h2>
Progeny are;</h2><h2>
XX, XY, X*X, X*Y
</h2><h2>
50 % males would be infected
</h2><h2>
50% male normal</h2><h2>
50% female normal,
</h2><h2>
50 female carrier.
</h2>
Explanation:
Hemophilia is an inherited disease and it follows an X-linked recessive pattern. The genes for hemophilia disease are located on the X chromosome. In males one mutated copy of the chromosome X is sufficient to cause the condition, because male contain only one gene. Female contain XX chromosome, so both the chromosome must have mutated for causing this disease.
According to study of Queen Victoria (1891-1901) of England, Alice's daughter Alix was X linked carrier and George V was normal male,
so if they got married, their children would be
parents genotype X X* XY
progeny
XX, XY, X*X, X*Y
50% males would be infected
50% male normal
50% female normal,
50 female carrier.
