You can do it! Make a plan and follow through. There are so many great resources out there. <3

Or is it because each will give us 1/8 probability so we add 1/8 + 1/8 to give us 1/16?

@@Topgear.filmer Do it in parts as I did in problem #2, So... if Aa x Aa , then there is 1/4 of a chance of getting AA; next- cross Bb with BB, and you will get Bb = 1/2, same for Cc. Multiply 1/4 x 1/2/x 1/2 = 1/16 for genotype AABbCc. Do the same for the other genotype and add them up. You will get 2/16. Simplify to 1/8. :)

Actually I just did the cross and found out the expected is going to be 1:1:1:1 because the homozygous recessive individual doesn't change anything; so every thing should be 1 to 1.

If genes are linked, they don't follow the expected Mendel's law of independent assortment.

Restriction enzymes have names and they are unique in a way that they can only recognize and cut a specific DNA sequence. Think of them as molecular scissors that seek out and cut only at a specific pattern. So if your unknown sample has the sequence that the restriction enzyme can recognize, it will be cut. If it does not have it, it will not be cut. If your linear DNA sample has 1 restriction site, it will be cut once and you will get 2 separate fragments. If your linear DNA sample has 3 restriction sites, it will cut 3 times and you will get a total of 4 fragments. To find out how many base pairs these fragments have, you will then run them through gel electrophoresis. :)

@@4EvaBio amazing! thanks for replying to me.. I am having trouble getting a well defined bands for my digestion product, I can see some separation but it is quite faint.

Check out my other video for more details to help you understand restriction enzymes, how they cut DNA and how DNA fragments run through the gel electrophoresis :) th-cam.com/video/2J5DSFCdgj8/w-d-xo.html

@@4EvaBio no I mean ..can you make a vedio on how we can detect homozygositt and hetrozygosity in bands while studing genetic diseases

Simply put.. Homozygous alleles(genes) show up as 1 band on the gel because they are the same size and run together through the gel. Heterozygous alleles are different... so they may have different sizes, hence show up as 2 separate bands. :)@@misbahfarooq1189

​​@@4EvaBiothank you..can I ask one thing more... What does non informative results or bands show. 2nd thing if there is no linkage what will be its explanation or how to justify it. Tomorrow is my m.phil defense.. Your help will be appreciated

unfortunately it cannot regenerate its lost part from small pieces made by a mixer .it has only some regeneration power
