According to Mendel’s principle of segregation, an Aa heterozygous diploid organism produces:

Group of answer choices

Only gametes that are AA

Only gametes that are aa

AA and aa gametes in theoretically equal numbers

A and a gametes in theoretically equal numbers

According to Mendel’s principle of independent assortment, a diploid organism with the genotype Aa Bb (the genes are located on different chromosomes) produces:

Group of answer choices

Only Ab and aB gametes

Only ab and AB gametes

AB, Ab, aB, and ab gametes

Group of answer choices

1A⁺ : 1A^-

1A⁺ : 3A^-

3A⁺ : 1A^-

Why is the interconnectedness of the brain critical to higher order function?

What do both G protein-coupled receptors and tyrosine kinase receptors have in common?

A chromosomally XY fetus with normally functioning testes has a mutation in the androgen receptor so it can't respond to testosterone (but it can still respond to MIS). Which of the following WILL develop by the time the child is born?

Select one:

a. A uterus

b. Fallopian tubes

c. A cletoris

d. An epididymis

What important difference appears to explain why some species form pair bonds and others don't?

Select one:

a. Species differences in the size of the nucleus accumbens

b. Species differences in the number and/or distribution of oxytocin and vasopressin receptors in the brain

c. Species differences in the circulating concentrations of oxytocin and vasopressin

Can you please explain the molecular components involved in the pathway of SsrA-tagged protein degradation in Vivo? Including the adaptor protein SspB and delivery to ClpX and subsequent degradation by ClpP.

BIO REVIEW SHEET 4

1. Define “taxonomy”.
2. Define “binomial nomenclature” and know how to properly write an organism’s scientific name.
3. List the major taxonomic categories or the current hierarchical classification system, from the most to least inclusive.
4. Describe Linnaeus’ original two kingdom classification and name two shortcomings of this scheme.
5. List three Domains
6. State the guidelines/rules for properly building a dichotomous key and/or identify errors in an example a dichotomous key and/or build a dichotomous key using a given set of specimens

The list below describes (in no particular order) some early events of the pre-embryonic period.

1 – Cortical reaction

2 – Blastocoel forms

3 – Yolk sac and amnion start to form

4 – Dichorionic-Diamnionic twins

5 – Four celled pre-embryo

6 – Human chorionic gonadotropin present in urine

The 6 steps above are not in the correct order.

Give a brief background on GMOs. What are they? What role do they play in our food production?

What are the Benefits/Drawbacks?

Do you think genetic modification experimentation is “unnatural” or interferes with the “balance of nature”?

Some genetically modified (GM) traits can also be produced by conventional crop breeding. In such a case is the GM crop bad and the conventional one good?

Why do you think the use of GMOs is still such a divisive topic?

Explain the precise meaning of the statement “The heritability of height in humans is 0.85”. In your answer you should indicate what proportions of the total phenotypic variance in height observed in the population is due to genetic variance and what proportion is due to environmental variance. Explain why heritability only tells you something about the population, and can’t be applied to a single individual. For example, explain why it makes no sense to say that a heritability of 0.85 means that 85% of your height is due to your genes and 15% of your height is due to the environment you developed in.

what is body segmentation? in what structures is segmentation represented in the bodies of annelids, arthropods and vertebrates?

Briefly discuss two mechanisms of post-translation modification of protein synthesis.
