Exploring Monohybrid and Dihybrid Crosses in Genetics

Who is known as the father of genetics?

• James Watson

• Charles Darwin

• Gregor Mendel

• Reginald Punnett

What was Mendel's approach to understanding genetics?

• Observing weather patterns

• Analyzing soil types

• Crossing different plant characters

• Studying animal behavior

Who developed the Punnett square technique?

• Francis Crick

• Reginald Punnett

• Charles Darwin

• Gregor Mendel

What is the purpose of using a Punnett square in genetics?

• To calculate mathematical equations

• To simplify genetic crosses

• To predict the weather

• To draw biological diagrams

What is the phenotypic ratio of a Monohybrid cross?

• 3:1

• 9:3:3:1

• 2:1

• 1:2:1

What does the genotype 'Tt' represent in a Monohybrid cross?

• None of the above

• Heterozygous

• Homozygous recessive

• Homozygous dominant

What does a Dihybrid cross involve?

• Crossing four characters at a time

• Crossing two characters at a time

• Crossing a single character

• Crossing two different species

Why is the Punnett square method preferred for Dihybrid crosses?

• It's visually appealing

• It simplifies complex genetic crosses

• It requires less knowledge of genetics

• It's faster than traditional methods

What is the phenotypic ratio obtained in a Dihybrid cross?

• 2:2:2:2

• 9:3:3:1

• 3:1

• 1:2:1

What does the presence of a recessive trait in the F2 generation of a Dihybrid cross indicate?

• Dominant genes are always expressed

• Phenotypic ratios are unpredictable

• Recessive traits can be expressed if both alleles are recessive

• Dihybrid crosses are inaccurate
