You are viewing a pedigree and trying to determine the inheritance pattern of a trait. List three characteristics that, if obser

Answer:

X linked inheritance is one of the mechanisms of the inheritance which is associated with the mutation of the gene present on the X chromosome.

The characteristics of the X linked recessive inheritance that must be observed in the pedigree analysis will be-

1. X linked trait is always passed from the mother to the sons (females to males)

2. The males (XY) are usually affected by the gene as only one copy of the recessive gene in males can show its effect.

3. Females are the carrier of the disease but they are not affected by the condition.

Serggg [28]

Dr. Haxton says the O-O bond is polar and the C-C bond is nonpolar. A good student would say ...

a.No, both bonds are highly polar.

b.Yes. O attracts electrons more strongly than C.

c.Right! O is electronegative, so O2 is polar.

d.Wrong again, Ralph. Both bonds are nonpolar. When two atoms of the same kind form a covalent bond, they share electrons equally because their electronegativity is the same.

e.No way. C is more electronegative than O.

Answer: d.Wrong again, Ralph. Both bonds are nonpolar. When two atoms of the same kind form a covalent bond, they share electrons equally because their electronegativity is the same.

Explanation:

Often when O and H are present in the substance at (opposite) ends (of the electronegativity scale), the polarity observed is very large, we can safely say the substance have a polar bond in it.
