If two individual are heterozygous for both traits then there genotype will each look like this PpLl. To find the probability, you need to do a cross with both traits. Each parent has the possibility of giving the following combinations: PL, Pl, pL, pl.
PL Pl pL pl
PL PPLL PPLl PpLL PpLl
Pl PPLl PPll PpLl Ppll
pL PpLL PpLl ppLL ppLl
pl PpLl Ppll ppLl ppll
Polka dot tail/ long lashes: 9/16
Polka dot tail/ short lashes: 3/16
Solid Tail / long lashes: 3/16
solid tail/ short lashes 1/16
The answer is (C) 9:3:3:1 ratio with 9 polka dot tails and long eyelashes, 3 polka dot tails and short eyelashes, 3 solid tails and long eyelashes (there seems to be a typo in the question) and 1 short tail short eyelash
The male<span> pelvis exhibit more prominent (pronounced) bone markings than the female pelvis because of the reason the male pelvis has larger leg muscles than the female pelvis. The male pelvis would exhibit more prominent bone markings because they have larger leg muscles.</span>
The 2 types of bone markings being identified would be the opening on the occipitomastoid suture in which the internal jugular veins would travel to carry the blood from one's brain to the heart and the Mandibular condyle of the mandible that would then form the temporomandibular joint.
