O Free-living bacteria and archaea have 1,500 to 7,500 genes. O Humans and other mammals have the highest gene density, or number of genes, in a given length of DNAD Question 23 What is predictive DNA Phenotyping?

In the long term evolution experiment, 12 replicate lines all started from the same mix of E.coli and were given the same growing conditions. There was no mixing between the replicate flasks. The cell volume was observed for the 12 replicates (different coloured lines on the graph) for the first 10,000 generations. Given these results, what can you conclude from the experiment? (more than one answer is possible) all lines have evolved increased cell volume we shouldn't be surprised by the consistent results in cell volume across the lines because all experience the same selection | genetic drift has occurred microevolution has occurred |there is no variation between the lines over the different generations in cell volumeQUESTION 2 DOK 1 Which of the following is NOT one of the benefits of transgenic crops?

- Codominance B B Copy link MULTIPLE CHOICE QUESTION W BW What is the difference between BW incomplete dominance and codominance? The dominant allele completely masks the recessive allele. WBW BW. In codominant traits both alleles are expressed, while in incompletely dominant traits the alleles mix to create a 3rd Voulbbe variation of the trait. In codominance the traits are mixed, in incomplete domiannce the traits are both expressed. Rewatch SubmitExtra Question Chapter 4 1.

- Question 11 What statement is FALSE regarding the use linkage mapping for human genetics? O The first linkage map showed the relative location of genetic markers. OA large number of chromosomes means that many traits assort independently, frustrating linkage mapping efforts. O Linkage mapping continues to be the preferred method to determine alleles associated with disease. Initial linkage mapping used family pedigrees. Question 12 Which of the following is not a component of Sanger sequencing?QUESTION 4 Is crossing over a good or a bad thing? A. a bad thing because it makes offspring with the wrong number of chromosomes O B. a good thing because it reduces the variety so each member of a species is as similar to the others as possible C. a bad thing because it mixes two kinds of DNA O D. a good thing because it creates lots of genetic combinations and varieties within a speciesQuestion 12 4) Listen 9.
