Answer:
The first thing to look at would be type of symmetry the organism exhibits. If it is asymmetrical then it would be a sponge and the discovery could stop right there. If not, other characteristics need to be investigated.
Knowing the type of body cavity this organism has would be helpful.
It would also be beneficial to know what type of skeleton (endo or exo) this organism has and what its appendages look like.
Finally, the type of digestive tract and the presence or absence of a head would help to determine what this creature is.
The question is the following :
<span>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.</span>
