The question is the following :
What is the best evidence to prove that Irene was heterozygous for hemophilia?
A) Alice carried the recessive allele.
B) Alexandra carried the recessive allele.
C) Frederick carried the recessive allele.
D) Waldemar carried the recessive allele.

The correct answer is A

In the pedigree, marked with blue are the carriers of the X recessive allele ( they have one X that has the mutation and the other that doesn't).
Alice was Irene's' mother, and since both Alice and iIrene have the allele, it is safe to conclude that Irene inherited the recessive allele from Alice.

Check all that are true statements regarding the differences between a typical female and male pelvis. rev: 10_24_2015_qc_cs-268

melisa1 [442]

Answer:

1. The female ileum does not project far above the sacroiliac joint

2. The body of the pubis is longer in females than in males

Explanation:

Pelvis refers to the complex of bones in the male and females of humans and other primates which joins the upper trunk to the legs. The pelvis allows the space for the urinary bladder, Intestine and the reproductive organs.

It is the presence of these reproductive organs and associated functions which changes the shape of the pelvis in male and female like the females have broader pelvis for the growth of the baby inside the womb and the childbirth whereas the males do not have wider but narrower bones.

The ilium bone in the females does not project far above the sacroiliac joint formed between the sacrum and the ilium bones.

Thus, the selected option is correct.
