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.
When lactose is not present, what happens to E. coli is that the genes that produce the enzymes needed to break down lactose are not expressed. The correct answer is B.
Answer:
Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
