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.
Answer:
Organisms mainly use two types of molecules for chemical energy: glucose and ATP. Both molecules are used as fuels throughout the living world. Both molecules are also key players in the process of photosynthesis.
Explanation:
The movement of water across a membrane.
In mitotic cell division, one parent cell produces <u>two identical </u><u>daughter </u><u>cells.</u>
The correct option is (d) Two identical daughter cells.
<h3>Mitotic cell division</h3>
- In mitosis, the cell divides into two identical daughter cell that contains the same number of chromosomes as the parent cell.
- It divides into five stages: prophase, metaphase, anaphase, telophase, and cytokinesis.
- The different stages of this cell division are together called as mitotic phase (M).
Thus, the correct option is (d) two identical daughter cells.
