Q7
in pigs, the number of teats and litter size are under genetic control. Each piglet must have ready access to a tear. british breeds of female pigs (sows) generally have 12 teats and 11 piglets each litter. Some of the traditional british breed of pigs have been crossed with the chinese meisham pig. chinese meisham sows have up to 18 teats and average 16 piglets each litter. this xbreeding has produced a hybrid pig called the manor meisham.with respect to these breeding exp, it is most likely that.
a. british farmers wanted to produce smaller size litters.
b. chinese farmers wanted to produce larger sized litters
c. british sows were mated with meisham males
d. meisham sows were mated with british males
I put D for that

I believe the gene cloning/DNA replication question was a matter of interpretation. It'd be DNA replication if the chromosome replicated as part of mitosis, but gene cloning if referring to the process of incorporating the DNA into the cells in order to clone it when the cells replicate.

Did you have to include no gene flow in the physical isolation?

I failed to include lack of gene flow. All I said was that members of each population could not cross the barrier, so I hope no gene flow is implied by that remark.

I was happy to see that VSSRIG question after it. Thanks, Munto. :D

You must state no gene flow.
You can't just imply it.

What was the VSSRIG qn?

There was no VSSRIG question??

There was something along the lines of it. I think it had something to do with how a new species could arise out of that geographic isolation (I think that's allopatric speciation).

Also, andrewloppol, I'm with you on DNA replication. :D

But Shiney says its cloning and its hard to doubt this guy...49...

Well I can't be sure. I'm just saying what's technically correct, but DNA replication COULD be accepted if they're lenient since it's partially correct and possibly due to what they expect of you at a VCE level.

Plus, I'm unaware of the context of the question as shown by;
I believe the gene cloning/DNA replication question was a matter of interpretation. It'd be DNA replication if the chromosome replicated as part of mitosis, but gene cloning if referring to the process of incorporating the DNA into the cells in order to clone it when the cells replicate.

I was under the impression that it was human-mediated? Probably just a bias I had from people saying cloning in the first place though.

Actually you don't I studied the steps in one of the VCAA assessment reports and it didn't have gene flow just physical isolation, something about selection of different phenotypes, can't interbreed after barrier removed or something.

I chose C. I presume the British sows were being mated with the Meisham males because British farmers wanted to produce larger sized litters. So, they would want to introduce the Meisham DNA into the British sows, rather than breeding British males with Meisham sows, which would produce offspring with smaller litter size.

Edit: goddamn I am wrong.

"number of teats and litter size are under genetic control" I think should be something to do with A or B

That's interesting?  Everywhere else in the solutions to those sorts of questions they put (1) after the no gene flow statement.
But if that's the case, oh well, I said both.

Me too.
def D. want to ensure all of litter have a teat, so meisham sows (more teats) will be bred with british males.

The Wagyu CHSI allele was isolated and given a fluorescent tag. it was introduced into a yeast cell as a large, independent, cytoplasmic chromosomal segment called a yeast artificial chromosome (YAC). in addition to the allelic DNA, a YAC includes a centromere and a replication sequence. the yeast cells are then incubated in the presence of growth stimulants and given time to replicate. this procedure is similar to genetic engineering of bacterial plasmids, however the YAC is able to contain much larger pieces of DNA than a plasmid.
cii bacterial plasmids lack a centromere. why are yacs made with a centromere
iii. what term describes the process of copying a gene

Reading that again, gene cloning.

It says physical isolated OR no gene flow from VCAA
