Question
Indicate whether each statement is True or False.
10. _____ A recessive phenotype can be expressed by some progeny of a monohybrid cross.
11. _____ Epistatic genes may result from dominant or recessive alleles.
12. _____ At a single locus, a diploid individual may have more than two different alleles.
13. _____ A temperature-sensitive allele is an example of a genotype x environment interaction.
14. _____ All of the genetic material in a eukaryotic cell is found in the nucleus.
15. _____ Sex-limited traits are, by definition, encoded by genes on the sex chromosomes.
16. _____ In some XX-XY species, genes on the X chromosome in females have one-half the
expression level of the same genes in males.
17. _____ Type 1 diabetes shows 53% concordance in monozygotic twins and 11% concordance in
dizygotic twins, suggesting that genetic variation has no effect on this trait.
18. _____ A gene can have more than two alleles in a population.
19. _____ Linked genes cannot have recombination frequencies that are higher than 50%.
