Hemophilia is an inheritable genetic disorder that prohibits the
proper formation of blood clots.
The recessive gene that causes hemophilia is located on the
X-chromosome. Given this
information, which of the following statements is true?
A. In order for the male offspring to be a
hemophiliac, his father must be a hemophiliac
B. In order for a female offspring to be a
hemophiliac, her father must be a hemophiliac.
C. In order for a male offspring to be a
hemophiliac, his mother must be a hemophiliac
D. In order for a female offspring to be a
hemophiliac, her mother must be a hemophiliac.
A. A
Gene B. a codon C.
a base pair
D. a nucleic acid
Which statement best describes a relationship between genetic
structures?
A. Both
genes and DNA are made of alleles
B. Both
alleles and DNA are made of genes
C. Both DNA
and alleles are made of chromosomes
D. Both
genes and chromosomes are made of DNA
What is supposed to be “funny”
about this? (What is the
function of a Punnett square) A punnett square is used to predict possible genetic outcomes of genetic cross
*Assume
that having swag is a Dominant trait. You obviously have a ton of Swag )Homozygous Dominant) and you have kidswith
someone that is Heterozygous for swag.What is the
genotypic ratio of your swag children?
1:1 Heterozygous: Homozygous Dominant What is the phenotypic ratio of your swag kids?
All your children will have swag.
I then talked a little about genetic disorders and how they are inherited in the same manor as what we have already talked about
Then i let you guys watch the video about the fainting goats!
Which lead us into a discussion about more complex forms of heredity. Obviously these goats have a gene that causes the myotonia. It is not always expressed though. When they are running around normally it is not a problem, but when they are frightened, this turns the myotonia gene On. More to come on this type of complex genetics. Here were some of the notes we continued through today
For any trait that you exhibit the dominant phenotype,
your two possible genotypes are HOMOZYGOUS DOMINANT (TT) or HOMOZYGOUS RECESSIVE (Tt)
For any trait that you exhibit the recessive phenotype
your only possible genotype is Homozygous Recessive Having six fingers on each hand instead of 5 is a dominant
allele.What are the chances that
two individuals with 5 fingers can have a 6 fingered child?
We then went through some of these slides - most of this was discussion. I was VERY impressed by how much you guys remember about punnett squares from 8th grade so we will be able to fly through this part of the chapter.
Which
structure in some unicellular eukaryotic organisms functions to maintain water
balance inside the cell?
A. Oral
groove C. macronucleus
B.
pseudopodia D. contractile vacuole After these we went through an inventory of our traits.
We first determined our phenotypes on each of these traits and THEN, based on those phenotypes, predicted our Genotypes. For any of the traits in which we exhibited the dominant phenotype there were TWO different genotypes we could have had - Heterozygous or Homozygous Dominant. Any trait that you exhibit the recessive phenotype there is only ONE possible genotype: Homozygous Recessive.
Fill in the blanks with either the term Genotype, Phenotype or
alleles (you will use some more than once)
Different forms of a gene are known as Alleles. These
can be either dominant or recessive.
The two Alleles a person has for a specific trait is known as their
Genotype. This determines their
Phenotype which is the trait that is expressed.
A plant with
purple flowers, when allowed to self-pollinate, produces only purple-flowering
offspring. Which statement BEST
describes the genotype of the original plant?
A. One gene for purple flower color is
present on one chromosome. (this is true - one gene for purple flower color must be present on one chromosome, but the question is asking about the genotype which would involve a discussion about BOTH alleles)
B. One nucleotide for purple flower color
is present on one chromosome. (Recall that a nucleotide is what DNA is made up of. Each gene contains hundreds or thousands of nucleotides.)
C. Two alleles for purple flower color are
present on homologous chromosomes
D. Two codons for purple flower color are
present on homologous chromosomes (We have not learned yet about codons, but you will find out that codons are a set of three nucleotides that code for an amino acids. This still does NOT describe a full gene or allele yet.)
KQOD
Using a Microscope, a student observes a small, green organelle in a plant cell. Which energy transformation most likely occurs first within the observed organelle?
A. ATP to Light
B. light To chemical
C. Heat to electrical
D. Chemical to chemical
To answer this question, first you had to recall what organelle is green - the chloroplast. THEN you had to recall what process occurs in the chloroplase - Photosynthesis. FINALLY you were to recall the energy transformation that occurs during photosynthesis (light to chemical)
We continued with some notes and discussion on the relationship between genotype and phenotype
No Daily Question quiz tomorrow - we will save that for next week (probably Wednesday)
Well I am back and we are chugging through this looong chapter!! Friday and Monday of last week you took your open notes quiz then started into some book work on the next section. Tuesday I had you finish up the book work and then today we started into discussion on this. Here is what today was like.
Wednesday March 6th
Hair color in
humans is inherited, while language is not. Of these two traits, which property does only hair
color have?
A.It is genetically encoded,
B. it provides a survival benefit,
C. it remains the same over time,
D. it has existed for many generations
žDuring meiosis
you will pass on ONE of your TWO alleles to your offspring. žIf you have a
dominant and a recessive allele, which of those do YOU express? The Dominant Allele
ž Explain how
you could have a child that expresses a recessive trait (for instance blue
eyes) that you and their other parent does NOT express.
If you have both the dominant and recessive allele, you will EXPRESS the dominant allele but could pass down your recessive allele. If you do that as well as the other parent, you could have a child that expresses a recessive trait that neither parent does) After this we went through a couple slides of notes but not very far seeing as we had a two hour delay. more to come tomorrow!
