Can genetic cross be used to determine whether mutation occurred on the same gene or different gene that affect a certain characteristic such as tail shape. In this scenario we are comparing data's obtained by 2 different individual to prove whether mutation is on the same gene or different.

Answer #1

Genetic cross can be used to determine whether mutation occurred on the same gene or different gene that affect a certain characteristic. Same genes are located at the same position in homologous chromosomes and recombination cannot occur at the same position. Recombination usually occurs during exchange of genetic material between two different chromosome or between two different locations within the same chromosome. So Recombination cannot occur in same gene. So If the result of the genetic cross showed that recombination occurs between two genes, then we can conclude that mutation occured on different genes.

Section C – Mutation of SARS-CoV-2 Over Time All viruses accumulate mutations over time, and different classes of viruses have different mutation rates based on the fidelity with which their genomes are replicated. Viral mutations can affect the accuracy of tests, the efficacy of vac- cines, and virulence (the ability to spread, the seriousness of illness, etc.). In this section you will compare a number of sequenced genomes from clinical samples during the first several months of the COVID-19 outbreak...

One common application for the chi-square test is a genetic cross. In this case, the statistical null hypothesis is that the observed results from the cross are the same as those expected, for example, the 3:1 ratio or 1:2:1 ratio for a Mendelian trait. Dr. William Cresko, a researcher at the University of Oregon, conducted several crosses between marine stickleback fish and freshwater stickleback fish. All marine stickleback fish have spines that protrude from the pelvis, which presumably serve as...

An ANOVA test is conducted to compare three different income tax software packages to determine whether there is any difference in the average time it takes to prepare income tax returns using the three different software packages. Ten different individuals' income tax returns are done by each of the three software packages and the time is recorded for each. Because individual tax returns are different the analysis has decided to block on individual returns. The computer results are shown below....

A nosocomial outbreak of bacteremia occurred in an adult oncology unit, and active surveillance for the presence of the causative pathogen was instituted by monitoring stools and perianal cultures of patients. Enterococcus faecium was isolated from stools in patients with bacteremia and 22 noninfected carriers. The stool isolates of bacteremic patients were found to be closely related to the respective blood isolates as determined by DNA typing techniques, in this case pulsed-field gel electrophoresis. Prior treatment with an aminoglycoside and...
