Understanding of Genetics Quiz

Match each scientific development with its key contributor or concept.

Conducted pea plant experiments
Structure of DNA identified

Gregor Mendel
Mid-20th century

Arrange these events in the order they contributed to genetics understanding.

Chromosomes observed during cell division
Mendel's pea plant experiments on inheritance
Genes placed on chromosomes
DNA structure discovered

View Answers:

What type of plant did Mendel use in his experiments to study inheritance?

Pea plants
Corn
Tomatoes
Beans

Mendel observed inheritance patterns by studying pea plants. What term did he use to describe the traits that were passed on unchanged?

Units
Cells
Chromosomes
DNA

In the early 20th century, scientists found that chromosomes and Mendel’s ‘units’ behaved similarly. What did this suggest?

That genes are located on chromosomes.
That DNA structure is spiral-shaped.
That chromosomes don't affect inheritance.
That Mendel's units only apply to plants.

Select all correct statements:

Mendel’s work with pea plants was only recognised posthumously.
Genes were initially referred to as 'units'.
DNA structure was identified in the early 20th century.
Chromosomes were first observed in the late 19th century.

Use some of the following answers to fill in the blanks:
Mendel, genes, units, chromosomes, dna, traits, pea plants

Mendel’s experiments with in the 19th century introduced the idea of heritable that determine .

Why was the importance of Mendel’s discovery with pea plants not recognised until after his death?

His findings were ahead of contemporary scientific understanding.
He published in a widely read journal.
Genetics was already a well-established field.
Chromosomes had already been observed in cells.

Match each concept to the corresponding stage in genetic understanding development.
