Punnett Squares

The video introduces the Punnett Square, a tool used to predict genetic traits in offspring. It explains how to use the square with an example of eye color inheritance, highlighting dominant and recessive genes. The video also covers Gregor Mendel's pioneering work in genetics with pea plants, explaining how he discovered key genetic principles through controlled experiments.

What is the primary purpose of a Punnett Square in genetics?

• To measure the height of a plant

• To calculate the age of a person

• To determine the weight of an organism

• To predict the likelihood of inherited traits

In a Punnett Square, what does a lowercase 'b' typically represent?

• Dominant blue eyes

• Recessive blue eyes

• Recessive brown eyes

• Dominant brown eyes

What is the outcome when a dominant and a recessive gene are present in a Punnett Square?

• The recessive gene is expressed

• Both genes are expressed equally

• The dominant gene is expressed

• Neither gene is expressed

Who is known as the father of genetics?

• Gregor Mendel

• Albert Einstein

• Charles Darwin

• Isaac Newton

Why did Gregor Mendel choose pea plants for his experiments?

• They grow very slowly

• They have a limited number of traits

• They produce a lot of seeds and are easily cross-pollinated

• They are difficult to cross-pollinate
