How does the fossil record corroborate phylogenetic history?
A. The timing of evolutionary events in the
fossil record is not consistent with the
branching order of a phylogenetic tree.
B. Events in the fossil record occur randomly
throughout a phylogenetic tree, so the two
are not related to one another.
C. Events that occur early in the fossil record
are represented by branching events nearer
to the root of a phylogenetic tree.
D. Events that occur early in the fossil record
are represented by branching events nearer
to the tips of a phylogenetic tree.
E. Fossil record events are too old to be
represented on phylogenetic trees, which
reconstruct the more recent past.

In cats an X-linked pair of alleles, B and b, control
color of fur. The alleles are incompletely dominant:B produces black, b produces yellow, and Bb produces tortoiseshell. (a) A yellow cat had a litter of two tortoiseshell and one yellow kittens. What is the sex of the yellow kitten? (b) A tortoiseshell cat brings home a litter of black, yellow, and tortoiseshell kittens. The color of which sex would tell you the color of the tomcat that produced them? (c) A yellow male is crossed with a tortoiseshell female. If the female has all male kittens in her litter of four, what color(s) would they be? What will be an ideal response?
