Front

What is the difference between mitosis and meiosis?

Back

Mitosis is a process of cell division that results in two identical daughter cells, while meiosis is a process that results in four genetically diverse gametes.

Front

Define homozygous and heterozygous genotypes.

Back

Homozygous genotypes have two identical alleles for a trait (e.g., BB or bb), while heterozygous genotypes have two different alleles (e.g., Bb).

Front

What is the role of alleles in genetics?

Back

Alleles are different versions of a gene that determine specific traits.

Front

Explain the concept of dominant and recessive traits.

Back

Dominant traits are expressed when at least one dominant allele is present, while recessive traits are only expressed when two recessive alleles are present.

Front

What is the significance of a Punnett square in genetics?

Back

A Punnett square is a tool used to predict the genotypes and phenotypes of offspring from genetic crosses.
