3. Why is understanding differences in allele frequencies in populations important? Include implications for diagnosis and what tests are considered diagnostic.
4. Why aren’t blood tests always used to diagnose HFI?
Homework Answers
3. Allele frequency is a proportion of the overall frequency of an allele on a hereditary locus in a populace.
Generally it is communicated as an extent or a rate.
In populace hereditary qualities, allele frequencies show the hereditary decent variety of an animal varieties populace or comparably the wealth of its genetic supply.
The frequencies of the considerable number of alleles of a given quality regularly are charted together as an allele recurrence circulation histogram.
Populace hereditary qualities examines the diverse "powers" that may prompt changes in the dispersion and frequencies of alleles - at the end of the day, to development.
Besides selection, these forces include genetic drift, mutation and migration.
4. A newer, non-invasive DNA test is readily becoming more available. While the DNA test is not diagnostic because negative results do not guarantee that one does not have HFI, positive results, along with clinical symptoms, are strong indicators of disease. A presumptive diagnosis can be made.

Q3.3. Recall the prediction: Allele frequencies change by genetic drift equally quickly in large populations and in small populations. Is this correct? Why or why not? Yes. Genetic drift is sampling error, and sampling error is unpredictable, no matter the population size. Yes. Small populations experience more sampling error, but large populations have more reproduction overall, leading to similar rates of allele frequency change. O No. In the ferret experiments, allele frequencies changed more quickly in the small populations than...
