Lesson 4: Gene Expression and Personal Traits
                 Practice Test
 
Question 1:
A haploid cell has
  A.Autosomal chromosomes only
  B.Two copies of autosomal                     chromosomes and one sex                     chromosome
  C.Sex chromosomes only
  D.One copy of each autosomal             chromosome and one sex             chromosome
Question 2:
Most cells in the human body
  A.Have 2 copies of each autosomal             chromosome and no sex             chromosomes
  B.Have one copy of each autosomal             chromosome and no sex             chromosome
  C.Have 2 copies of each autosomal             chromosome and two sex             chromosomes
   D.Have 2 copies of each autosomal             chromosome and one sex             chromosomes
Question 3:
If you are heterozygous for a gene that has one recessive and one dominant allele, your body is most likely to
  A.Develop the dominant trait
  B.Develop a partial version of the             dominant trait
  C.Develop the recessive trait and             dominant trait
  D.Develop the recessive trait
Question 4:
A polygenic trait is produced by
  A.A gene that has multiple alleles
  B.A gene that is present as multiple                copies in the genome
  C.Contributions from multiple
            different genes
  D.A gene that is influenced by
            multiple environmental factors
 

Question 5 - 10:

For human blood group types, A and B are co-dominant alleles whereas O is recessive.  Match each genotype to its corresponding phenotype (on the right).
