Let H= No Hemophilia
h= Hemophilia
Now we will create the genotypes for the parents, it says that the mother is heterozygous which means she will carry the dominant and recessive allele, which would be Hh and it says the father is normal which would mean that he would be No Hemophilia dominant, so it would be HH
Cross the 2 created genotypes: Hh x HH
Now create your Punnett square using the 2 created genotypes above
H h
H HH Hh
H HH Hh
Looking at the Punnett square above, it appears that there’s a 2:2 ratio or a 50% chance of having Hemophilia and not having Hemophilia
So for a female child: 1/2 x 1/2= 1/4 of having a female with Hemophilia
The first one represents the female child having Hemophilia or not, that one can be obtained by simplifying the 2:2 ratio to a 1:1 ratio and the other one represents the chances of their child being a female. I assume that the steps above would be repeated again for the male child.
I hope that helps!
The correct answer for this question would be option B. Greenhouse gases are needed for the survival of life on Earth because without greenhouse gases, Earth would be too cold for life to exist. Hope this answers the question. Have a nice day.
It is a compound made of twenty-four total atoms
<u>Answer:</u> B. Pond
<u>Reasoning:</u> A lake is typically large and have a large dept, same with an ocean(But an ocean is much larger) so the temperature won't be constant.
A lagoon is a moving body of water that covers small bodys of sand or coral.
