(1) Gregor Mendel was contemporary of

	(a) Charles Darwin.
	(b) Albert Einstein.
	(c) Dmitri Mendeleev.
	(d) Democritus.

(2) What does "genotype" refer to?

	(a) the DNA of an organism
	(b) the genetic make-up of an organism
	(c) the type of gene in question
	(d) the order of genes

(3) Mendel's First Law states that the factors that determine physical traits are carried only by sperm cells.

	(a) true
	(b) false

(4) When two organisms are crossed, the offspring are referred to as

	(a) the F2 generation
	(b) recessive.
	(c) the F1 generation.
	(d) a genotype.

(5) Mendel believed that physical traits are determined by

	(a) inheritance of factors from both parents.
	(b) inheritance of factors from the male parent only.
	(c) inheritance of factors from one parent.
	(d) inheritance of factors from the female parent only.

(6) Female and male reproductive cells are called

	(a) phenotype
	(b) genotype.
	(c) alleles.
	(d) gametes.

(7) Which of the following describes variations of a gene type?

	(a) allele
	(b) genotype
	(c) phenotype
	(d) cross

(8) If two crossed alleles are the same, what is the genotype called?

	(a) homozygous
	(b) heterozygous
	(c) herozygous
	(d) phenotype

(9) A chart used to determine the offspring of a genetic cross is called a

	(a) cross chart
	(b) Punnet square.
	(c) periodic table.
	(d) Genetic square.

(10) Mendel's Second Law states that alleles randomly and independently segregate into an organism's gametes.

	(a) true
	(b) false

(11) Incomplete dominance results in

	(a) a trait that is a mix of those seen in the parent
	(b) the offspring having a different trait than either parent.
	(c) both of the choices

(12) If snapdragons demonstrate incomplete dominance in flower color, what would be the result of a cross between a red-flowered snapdragon with a white-flowered snapdragon?

	(a) All the offspring will have white flowers
	(b) All the offspring will have pink flowers.
	(c) All the offspring will have red flowers.
	(d) Three-fourths of the offspring will have red flowers and one-fourth will have white flowers.

(13) One reason Mendel's work was significant was because

	(a) it explained why only certain traits are passed down from each parent.
	(b) it resulted in the creation of the Punnett square.
	(c) it showed that physical traits are inherited from both parents.
	(d) it showed that the "miniature being" theory was accurate.

Quotes

My scientific studies have afforded me great gratification; and I am convinced that it will not be long before the whole world acknowledges the results of my work.
