DNA is a negatively-charged molecule. Also cell membranes are negatively charged. The problem would be how to push this charges together? I<span>f you put some CaCl2 into the mixture, the CaCl2 will "split" giving 2Cl- and Ca2+. This last ion will be attracted by the negatively charged DNA and will "cover" it, hiding its negative charge. Hope this answers the question.</span>
Answer:
Jane: Aa
Matthew: aa
Explanation:
Jane is a heterozygous woman, which means that she is dominant for this genetic trait while Matthew is homozygous that did not inherit the achondroplastic dwarfism trait from his parents, that is why he is alive.

a ║ aa ║ aa
So the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set
