1. Members of the same species which are capable of interbreeding is best described as an
community
population
ecosystem
biosphere
intron
2. If 16% of the persons in a population show a recessive trait, what is the allelic frequency for the dominant allele?
4%
16%
84%
96%
99%
3. For a particular human population, if the allelic frequency of the O allele for blood type was .1, and the frequency for the B allele was .5, what would be the allelic frequency for the A allele?
.1 (این یک دهم هست )
.2
.3
.4
.5
4. In the following population, what would be the allelic frequency for the dominant allele? 20 homozygous recessives; 320 homozyous dominants; 160 heterozygotes
10%
20%
60%
70%
80%
5. If four percent of a population shows a recessive trait, what will be the frequency of carriers in the following generation?
4%
8%
16%
32%
64%
6. If there is only one allele for a gene in a population, that gene is referred to as:
monoallelic
fixed
common
monocistronic
histoincompatible
7. Which of the following would cause deviation from the Hardy-Weinberg equilibrium?
small population
isolated
random mating
lack of selection pressure
no mutations
8. If 36% of the population is heterozygotes for a certain gene, what percentage of the population will show the recessive phenotype in the next generation?
4%
8%
16%
34%
need more information to determine
9. Which of the following formulas lets you predict the genotypic frequency of the next generation?
p + q = 1
X2 = sum [(o - e)2 / e]
p2 + 2pq + q2 = 1
d = 0.5 lambda / n * sin (theta)
e = mc2
10. The total aggregate of alleles in a population is referred to as:
the gene pool
the allelic frequency
the genotypic frequency
the genetic structure
none of these
