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

which alleles are

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 self-

pollinated, 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
