Question

8. The Chi-square value for theses data is a. 0.28 b. 0.51 c. 3.2 d. 1.12 e. 9.6
PROBABILITY
df 0.95 0.90 0.50 0.25 0.05
1 .004 .016 .455 1.32 3.84
2 .103 .211 1.39 2.77 5.99
3 .352 .584 2.37 4.11 7.81
9. The probability that the hypothesis - single locus, two allele with dominance and recessiveness PLUS sampling error are an adequate explanation of these data
is a. between 0.50 – 0.25 b. less than 0.05 c. between 0.95 – 0.90
d. greater than 0.95 e. between 0.90 – 0.50
10. The chi-square distribution relates
a. genetics to statistics. b. deviation from theoretical value to probability.
c. the probability of producing the same data when the cross is repeated.
d. random error to theoretical expectation. e. bases to sugars
11. A biochemical modification to DNA which occurs while maternal and paternal genomes are separated causes maternally and paternally derived alleles to be differentially expressed in the offspring. This phenomenon is known as
a. disjunction b. imprinting c. anticipation d. gendoscopy e. pluripotency
12. Diploid zygotes having genes derived from only one parent fail to develop normally. When ova are induced to divide partheno-genetically, the embryonic body begins to grow, but the extra-embryonic membranes fail to develop. If, on the other hand, a maternal pronucleus is removed and replaced by one of paternal origin, only the extra-embryonic membranes grow. Both male and female parental genomes are required for normal development in mammals. In some recessive disorders, the parent of origin affects allelic expression; that is: If you get the disease allele from one parent you will have the disease, but you will not express the disease if you receive the allele from the other parent. This is the result of CpG ____________. a. methylation b. nitrification c. depurination
d. slippage e. overload

Explanation / Answer

9) a. btw .50 &.25 11) b. imprinting 12) a. methylation :)
