Understanding Mendelian Genetics

The video tutorial explains Mendelian inheritance using pea plants. Gregor Mendel's experiments with pure yellow and green pea breeds demonstrate how dominant and recessive traits are passed through generations. The F1 generation, resulting from crossing pure breeds, is entirely yellow, indicating yellow as the dominant trait. A Punnett Square is used to illustrate the genetic makeup of the F2 generation, which shows a 3:1 ratio of yellow to green peas. The video concludes with a suggestion to explore more about Mendelian genetics through additional resources.

What was the result when Mendel crossed pure yellow and green pea breeds?

• Offspring were 50% yellow and 50% green.

• Offspring were a mix of yellow and green.

• All offspring were green.

• All offspring were yellow.

What does the term 'pure' mean in the context of Mendel's pea breeds?

• The breed can produce different colored peas.

• The breed can only produce peas of the same color when self-pollinated.

• The breed is genetically modified.

• The breed is resistant to diseases.

What was the observed ratio of yellow to green peas in the next generation after interbreeding?

• 25% yellow and 75% green

• 100% yellow

• 50% yellow and 50% green

• 75% yellow and 25% green
