^^ *Explanation

# data[].attributes.body
how about we are about to see a STAGE 3 EXPIATION!? I am mind blown!!!!!

# data[].attributes.body
about that crispr...

# data[].attributes.body
sooooooo

# data[].attributes.body
so what?

# data[].attributes.body
so

# data[].attributes.body
What about genetic diversity in crispr?

# data[].attributes.body
I am excited

# data[].attributes.body
and selective breeding is kind of like inbreeding because only a few are being selected to produce the next generation

# data[].attributes.body
i agree genetic diversity is lowered in the population. Because all the offspring are being produced by only a few parents, so some diversity the other adults had in their genome won't get passed on. some of their alleles could be lost.

# data[].attributes.body
How will it effect genetic diversity?

# data[].attributes.body
Genetic Diversity is lowered because of how there is only 1 variable not 2, to make different genes you need two difference genetics?  I am guessing haha

# data[].attributes.body
ok that was confusing!

# data[].attributes.body
Because where will the women be? and maybe everyone ill have the same traits as the men and no women traits?

# data[].attributes.body
Yes I agree^

# data[].attributes.body
Genetic diversity is lowered.

# data[].attributes.body
You can all answer that one :P It's a race

# data[].attributes.body
How does inbreeding (and selelctive breeding using maybe just a few males) affect genetic diversity??

# data[].attributes.body
Inbreeding is when offspring are bred with those who have very similar genes (brother, mother/sister, father). Inbreeding may result in the offspring being affected by deleterious recessive traits and can cause problems such as inbreeding depression which is the reduced survival and fertility of offspring.

# data[].attributes.body
if it's a capital it's a dominant allele, if it's a lower case it is representing a recessive alle

# data[].attributes.body
doesn't matter what letter is used

# data[].attributes.body
letters are used to symbolise alleles

# data[].attributes.body
what does ss stand for?

# data[].attributes.body
But if some were white then maybe the parent was Ss and sometimes passed on the s allele, which shows up because the test cross parent was ss too.

# data[].attributes.body
Then if all the babies of those two are spotted you know the first cow was SS coz they could only pass on the dominant S allele which makes all the babies spotted too.

# data[].attributes.body
Okay thankyou

# data[].attributes.body
Crispr technology, delivery, cell repair, in/out

# data[].attributes.body
So if you cross it with another cow that shows the recessive phenotype like no spots and being all white then the farmer knows that cow is ss.

# data[].attributes.body
Ohhhhh thankyou

# data[].attributes.body
Farmers or scientists could do a test cross if they want to find out what alleles an animal has for a dominant trait. Like spotted coats. If having spots is a dominant trait then that cow could be SS or Ss and at first you don't know.

# data[].attributes.body
Outbreeding is breeding from parents not closely related

# data[].attributes.body
inbreeding is breeding from closely related animal or species over the many generations it has passed from.

# data[].attributes.body
thankyou^

# data[].attributes.body
I can help with test crosses

# data[].attributes.body
What does what do?

# data[].attributes.body
What does it do?

# data[].attributes.body
What is an easy way to remember genome sequencing? - a genome is ALL the genes that an organism has (and they sound similar, gene, genome..) and sequencing is putting in order, or finding the order of. Like a sequence of numbers.

# data[].attributes.body
Cas9 is an enzyme

# data[].attributes.body
Inbreeding and out breeding please explain

# data[].attributes.body
what is Cas9

# data[].attributes.body
MAS and QTL? WHAAATT??

# data[].attributes.body
I am still confused about how QTL mapping works and what the markers do

# data[].attributes.body
What is an easy way to remember genome sequencing

# data[].attributes.body
CRISPR is made up of two things
1. Enzyme
2. gRNA

# data[].attributes.body
I am just wondering what is Test crosses? Please I am in need of help haha

# data[].attributes.body
what is mendelian genetics?

# data[].attributes.body
hi

# data[].attributes.body
sup guys
