Cycloalkanes
are saturated hydrocarbons with monocyclic structure.
<span>This
means that cycloalkanes contain hydrogen and carbon atoms arranged in a
structure containing a single ring (sometimes with side chains), with all of
the carbon-carbon bonds single. The examples of cycloalkanes are cyclopropane,
cyclobutane, cyclopentane, cyclohexane…</span>
Answer:
B) On the same place on the same chromosome.
Explanation:
Both alleles are located on the same chromosome and present at the same place because genes come in pair. Each pair of gene is located at a specific place on a chromosome. If the two alleles present at a specific location are similar to each other, it is called homo-zygous while on the other hand, if both alleles are different from one another, they are considered as hetero-zygous.
One affects radicle (root) growth while the other affects plumule shoot growth.
Color blindness is a recessive x-linked trait in humans. In a family where the mother is color-blind, and the father is normal, the probability of their having a color-blind son is 100%.
Color blindness is a recessive x chromosome liked recessive disease which is more prone in males than in females. As the mother is color-blind she has both the alleles of colorblindness while the father is normal with both x chromosome and y chromosome normal.
So if the parents have a boy, he will always receive an x chromosome with colorblindness gene from the mother and a normal y chromosome from the father always. Thus, the probability of having a colorblind boy will be 100%.
