what aspects of the pea plant made them a particularly suitable organism for Mendel to use
in his experiments?
what is meant by self-fertilization?
what aspects of the structure of the pea plant made self-fertilization the most common way
this plant reproduces?
what is meant by cross-fertilization?
what is meant by a "true-breeding" plant?
what is meant by hybrids?
what is meant by the terms parental (P) generation, F 1 generation and F 2 generation?
Mendel's principle of segregation describes inheritance of a single characteristic

what are the four hypotheses that Mendel developed based on his work tracking the
inheritance of a single trait?
what is a monohybrid cross?
what is an allele?
what is a dominant allele?
what is a recessive allele?
what is a Punnet square and what is it used for?
what is meant by the term phenotype?
what is meant by the term genotype?
be able to define, recognize and apply the terms heterozygous, homozygous dominant and
homozygous recessive
what was the genotype and phenotype of Mendel's true-breeding purple flowered plant?
what was the genotype and phenotype of Mendel's true-breeding white flowered plant?
when Mendel crossed a true-breeding purple flowered plant with a true-breeding white
flowered plant, what genotype(s) and phenotype(s) did he observe in the F 1 generation and
in what frequencies?
when Mendel crossed to members of the F 1 generation of his cross between the truebreeding purple and true-breeding white flowered plants, flowered plant, what genotype(s)
and phenotype(s) did he observe in the F 2 generation and in what frequencies?
what are phenotypic and genotypic ratios and be able to them based on given information
what is stated in Mendel's principle of segregation?
know how a Punnett square is set up and executed for a monohybrid cross and be able to
interpret the resulting information
Homologous chromosomes bear the two alleles for each characteristic
•
•
do homologous chromosomes carry genes for more than one trait?
are alleles for a given trait carried at the same loci on homologous chromosomes?
•
do the homologous chromosomes that are inherited from each parent carry identical allele
for each characteristic?
The principle of independent assortment is revealed by tracking two characteristics at
once
•
•
•
•
•
what is a dihybrid cross?
can a Punnett square be used in a dihybrid cross?
when Mendel conducted a dihybrid cross between two pea plants that were each truebreeding for two traits, what genotypes and phenotypes did he observe in the F 1 and F 2
generations and in what frequencies?
know how a Punnett square is set up and executed for a dihybrid cross and be able to
interpret the resulting information
what is stated by Mendel's principle of independent assortment
