Mendels Genetics

Who was Gregor Medel

• A scientist and priest who studies pea plant traits.

• The "father" of modern genetics.

• He discovered patterns of inheritance.

• All of the statements above are correct.

What was the main pattern Mendel discovered? (Choose more than one.)

• Two pea plants would have exactly the same kind of offspring?

• Each parent gives 1/2 of their directions/code for traits to the offspring.

• He could make a good hypothesis what the offspring might look like using the Law of Probability and Punnett squares.

• Pea plants could show totally different traits than the parent plant had.

While Mendel was alive what was true of his work as a scientist. (Pick more than one.)

• He had several students learning his methods from him.

• His work was ignored for years until about 1900.

• A college was opened and other scientists worked with him.

• He was a researcher who documented great notes we still use today in the study of modern genetics.

Mendel crossed two hybrid yellow seeded plants (Yy) and using probability he discovered....

• All the new plants were yellow (Y) (100%) 4:4

• One of the new plants was green (yy) 25% 1:4

• None of the plants grew at all.

• All of the new plants were green (yy) 100% 4:4

What is the chance a coin will land heads up?

• 100%

• 25%

• 33%

• 50%

A dominant gene is written on a Punnett Square as a:

• Capital letter (Y)

• Percentage (%)

• Lower case letter (y)

• A number (#)

A recessive trait is written on a Punnett Square as a:

• Capital letter (Y)

• A percentage (%)

• A lower case letter (y)

• A number (#)

Explain the KEY IDEA that the probability of one event DOES NOT affect the results of the next.
