We've just finished covering the inheritable syndromes from non disjunction. What we're
going to find by the end of today is that the assumption that everyone of the same
genetic species has the same map is not true.
The human genome project was completed
Grab the study guide!
This course is an overview of Genetics. This is a 3000 level survey course. We can't
cover all information in a one term class. This should be a two to three term course
because the amount of material is gigantic. It has its fingers
We should look at the first exam on the course pack to see what the format is like. We
should have no handwriting on the left page of our lab notebooks. You can put graphs
and things you produce on the left page. Anything you paste should go on the left p
We were talking about lethal alleles last time. We will now cover more interesting
aspects. The average lethal alleles are calculated to be about 4 per human. The
alleles are not an issue, for the recessive lethal alleles we possess are most likely
We introduced sex linkage last week and we had seen essentially something
noteworthy in the first cross in NOTES 5.1, and something different in the second cross.
The frame of reference is that we are talking about the mutations in these crosses. We
Do Drosophila prep for the lab before the first notebook check. Do the prep for the lab
as soon as possible!
We are starting with NOTES 4.1. We had started there last time before leaving. Each of
the chromosomes by the end of prophase 1 each chromosomes i
There is also a course pack on academic share. There are things we might want to
scribble on. Notes could be easier on them as well. The figures he shows us get
complicated. One of the first figures on there is the phenylalanine pathway on there.
We began with reviewing the wild type and mutant notations. We always name the gene
after the mutant. We are performing a cross of a wild type and mutant (green and yellow
respectively). The F2 are 3:1 again. This is just a change in notation. Wild type h
We have a quiz tomorrow! Today's lecture will determine what will be on the quiz. Prep
the tetrad lab! It is very short and quick to prep.
At the end of class last time, we talked about gene and environment interactions.
Simple or basic traits can be affe
DROSOPHILA MALES CANNOT PERFORM CROSSOVER. Male Drosophila do not
cross over. Drosophila still have physical linkage, and they have genetic linkage in a
sense. 2 Loci even on a large chromosomes always travel together. Cross over never
separates the allel
We will begin talking about splicing. What we are looking at in green is an intron in
figure 12.21. Introns that we find in prokaryotes are non homologous. We call them
introns because they are non coding information within a gene. They have arisen
MAKE SURE I STUDY COMPLEMENTARITY. I failed it on the quiz. We are looking at
a polyribosome in figure 13.21. There are ribosomes attaching to an RNA that is being
transcribed in a prokaryote. As soon as transcription starts, a large subunit can get put
zMake sure our notebooks are up to date. Pedigree analysis.
Last time were were talking about replication.We had talked about origins and initiation
of replication. We had talked about helices. We had talked about topoisomerase. We
are walking through a p
We will briefly talk about one of the kinds of extra nuclear inheritance. It is uniparental
inheritance. Maternal haplotype is mitochondrial type. Things that recombine become
more problematic to study. Knowing the inheritance of a given locus becomes
We are going to talk about how we can build pathways now. We've been studying them
and know the basics. These are logic problems more than anything. We are going to
see is that these kinds off experiments go hand in hand with other kinds of things we
We talked briefly about prokaryotes last time. Remember the three major kinds of sex
among them. Don't worry about quantitative problems here.
We're still in transmission genetics. We are still talking about about the transmission of
genetics from one gen
The Secret life of Twins: Natural Similarities
1. Identical twins are clones of each other,studying twins help scientist to understand how genetics
plays a role in our lifes.
2.Fraternal twins come from separate egg fertilized by separate s
