Name the error in meiosis that
caused this disorder
The diagram below shows a cellular process
that occurs in organisms. This process is
known as
 Mitosis
 Meiosis
 Fertilization
 Photosynthesis
The diagram below shows homologous chromosomes
during prophase I of meiosis. Which of the following
correctly describes the process being illustrated?
A. Mutation in which
the DNA content of
the gene is altered.
B. Segregation of sister
chromatids
C. Condensation and
segregation of
alleles
D. Crossing over in

exchanged
Mendel arrived at the conclusion that the two
elements affecting a particular trait are
separated during gamete formation. This has
since been confirmed by the discovery of
 [A] eggs and sperm
 [B] mitosis
 [C] fertilization
 [D] meiosis
Mendel concluded that genes for two or more
different traits assort independently of one
another at gamete formation. He reached
this conclusion because none of the garden
pea traits he studied were
 [A] visible
 [B] recessive
 [C] codominant
 [D] linked
Mendel’s second experiment with pea plants was a dihybrid
cross in which he crossed two true breeding parents with
contrasting forms for two traits. The F 1 hybrids all showed the
dominant form for both traits. When the F 1 was selfpollinated, the F 2 offspring showed four phenotypes in the
ratio of 9/16; 3/16; 3/16; 1/16. Which principle resulted from
this experiment?
 [A] recessive alleles
 [B] dominance
 [C] linkage
 [D] independent assortment
