Sorry....I had a response typed out and then saw where you had written "Not" a Punnett square. oops!!

I am getting ready to retake the Teas test at the end of this month. I am trying to find some info on a science question. It was about predicting future offspring..it wasnt a punett square though..the name of it or any info on it would be much greatly appreciated.
thank you in advance,

are you talking about the pedigree chart?

I remember there is a question about a genetic disease that pass down among family member,

I had this question (this is the best I could recall) on one of my tests:

What is the probability that the grandchild will be infected?

The possible answers were:

a. 25%

b. 50%

c. 75%

d. 100%

100% is the correct answer

the disease is being passed down each generation, doesn't matter whether the grandchild is male or female, still would get infected

thank you so much for helping me with this problem. the more that i can remember and get correct the better off i am. will it be the same test that i took before? i have heard so many different answers! also do u remember the one about where they were asking about the neurtons what number it would be..it had a letter and then a slash at the top and a slash at the bottom. i was reading and i found that you are suppose to subtract the two to get the number for the neutrons? so confused.

thank you all so much for the help

Are you talking about Atomic Number / Atomic Mass?

Atomic Number is the number of protons and atomic mass is the overall weight of Protons and Neutrons and the numbers after the decimal are the weight of the electrons.

Example.... Carbon © has an atomic weight of 12.011

The atomic number would be 6 because there are 6 protons.

The atomic mass is 12 because there are 6 protons and 6 neutrons in the nucleus.

the .011 is the weight of electrons. (You usually dont have to worry about that part)

Is this the problem? Find the number of neutrons of Z?

Z(65 on the top) (30 on the bottom)

65-30 = 35 neutrons

lil_ash03 · Mar 18, 2008

i think that is the one..they had like 2 numbers or dashes i cant remember and i had to find the one that was the neutrons. i had read online that you are suppose to subtract but i was really sure and really trying to boost that score as much as possible!

thank you so much for the insight on these questions
