BIO 3300 – Genetics Questions with Correct Answers
Mendelian traits Correct Answer-A gene with two different alleles
- simple dom. / recessive relationship
Non-Mendelian Traits Correct Answer-Do not express ratios expected
from mendelian inheritance
Loss of function allele Correct Answer-type of lethal alleles, encode
proteins necessary for survival
gain of function allele Correct Answer-protein encoded by mutant gene
changed so it gains new function
wild-type allele Correct Answer-prevalent alleles in a population
mutant allele Correct Answer-altered by mutation; recessive
lethal allele Correct Answer-can cause death; loss of function

homozygous white crosses to make pink plowers
overdominace (heterozygote advantage) Correct Answer-Ratio 1:2:1
- heterozygotes has trait that results in greater reproductive success than
either homozygotes
example of overdominance Correct Answer-increased resistance to
infection
Codominance Correct Answer-Ratio 1:2:1
a heterozygote expresses both allele simultaneously without forming
phenotype
example of codominance Correct Answer-encodes proteins that function
slightly differ each other
