Genetics Exam test queries and answers graded
A+
1. chi-square What type of test would you use to determine whether observed data
analy- sis constitute evidence of genetic linkage or are simply a case of chance
variation from expected values?
2. AZ/az The syntenic genes A and Z are linked. A cross between two parents
AAZZ and aazz, produces F1 progeny with the AaZz genotype. What are
the possible arrangements of alleles on the F1 progeny's
chromosomes?
3. 38.25% Genes A and B are located 10cM from each other on a chromosome.
Gene C is located 25cM from gene A and 15cM from gene B. Assuming
that I = 0, what is the probability that the tri-hybrid ABC/abc will
produce ABC gamete?
4. they are far Syntenic genes can assort independently when .

genes.
5. Genes b and c are A competent Hemophilus strain is individually transformed by three
genes (a, b,
farthest apart and c) at a rate of 0.002% each. However, cotransformation frequencies for each
pair are as follows:
a and b 0.38%
a and c 0.72%
b and c 0.19%
What is the correction conclusion from this data?
