No. As lexitu mentioned in the previous post, VCAA prefers P. Robustus (P denotes "robust" australoptiches, now largely regarded as a seperate genus from A)
Large list of questions coming up (last long list before exam)
thanks in advance!
1) does VCAA regards A. Africanus as the ancestor of Homo sapiens or P. Robustus ?
2) Can aneuploids typically produce offspring?
E.g. A person with a DS has three 21 chromosomes but can still be fertile... how does this work?
3) Do plants usually have sex chromosomes? And do those without tend to self fertilise?
4) Can a population bottleneck NOT arising from chance still be referred to as such?
If so, are there two types of population bottlenecks, only one of which refers to genetic drift?
5) Can genetic isolation refer to genetic isolation at that point in time (e.g. when seperated geographically?)
6) Are anticodons read in 3'->5' or 5'->3' end by convention?
7) Do prokaryotes have non - coding regions? i have notes saying NO, but if you think about it, the region between the promoter and the genes in an operon must be "non coding".... ?
8)is DNA hybridisation usually done with cDNA & cDNA
9) Can transgenic refer to organisms who have mutated (or alternate) forms of genes from their own species?
10) In plants are fruit the in effect container of new plants? So a fertilised flower develops into a fruit with "MATERNAL" genotype containing seeds which can each develop into new plants (and are diploid)
11) Does different alleles have to have different results on phenotypes ? (in homozygous state)
12) Do sexually reproducing organisms in a STABLE or VARIABLE environment have greater variation?
I said stable as it would allow maintanence of a wider variety of phenotypes, but the book says Variable.. though if it was variable wouldn't that mean only the middle phenotype is acceptable (at every given point in time, as extremes are effectively completely eliminated).
Thanks a lot!
