The condenser lens, is placed between the light source and the specimen and it gathers and focuses the light rays in the plane of the microscopic field to view the specimen.
According to my 9th grade biology knowledge,
The answer to this question is A: They have a recent common ancestor.
Cystic fibrosis is a recessive condition; meaning if a
dominant condition takes over it will not be seen in the offspring. The man
genotype with cystic fibrosis can only be this: cc (when c is equal to the cystic fibrosis and C is equal to not
having one). The woman with no history of cystic fibrosis can possibly have
either of these two genotypes: Cc or CC.
To see their offspring’s possible genotype, we’ll use a
punnett square let’s start with Cc:
C c
c Cc cc
c Cc cc There
is a 50 % chance of the child having cystic fibrosis.
To see their offsprings possible genotype with CC:
C C
c Cc Cc
c Cc Cc There
is no chance that the child will have cystic fibrosis.
