Which stage of weaning is measuring predictors of weaning readiness?

What is the easiest and most powerful single predictor of weaning outcome?

Dr. Wassarman conducted a GWAS in Drosophila to identify genetic variants that influence early mortality after traumatic brain injury. He included 179 inbred lines in his GWAS (i.e., the DGRP lines). In the figure below, which of the fly lines indicated by the three arrows contains a genome with either the greatest number of protective genetic variants and/or protective genetic variants with the biggest effect size?

A mouse model of Fragile X Syndrome exhibits the repetitive behavior of excessive marble burying. In class, we discussed how scientists alleviated this symptom in the mouse model using the CRISPR-Cas9 system. The figure below shows some of the data we discussed. First: Label the bars in the above bar graph by matching the letter that corresponds with each bar to the genotype to which that bar refers. Bar A refers to [Wildtypecontrolmice] Bar B referes to [WTCas9] Bar C refers to [FMR1knockoutmice] Bar D refers to [FRM1Cas9] Second: Select the best answer to the question below from the dropdown menu. How did the researchers deliver the CRISPR-Cas9 components to the mice? [2nd]

Consider the process of RNA Interference. Match the description on the left with the best term on the right. Each term will only be used once.

Consider CRISPR-Cas9 technology. Match the description on the left with the best term on the right. Each term will only be used once.

A modifier screen is a type of forward genetics. The main difference between a forward genetic screen and a modifier screens is:

To get from correlation to cause, scientists must do reverse-genetic experiments. Cao et al. wondered if increased antimicrobial peptide (AMP) expression in dnr-1 mutants caused neurodegeneration.  How did they answer this question?

List four general side effects of radiation therapy.

Bonus Question: This question will not count against you. Answering the question correctly will award you an additional 5 points to your raw score. You may use scratch paper to draw a dihybrid cross if needed.  If the genotypes of these two parents is AaBb x AaBb, what ratio would represent the expected PHENOTYPIC outcomes?
