Meiosis and mendel/heredity review

Front

What is the difference between genotype and phenotype?

Back

Genotype is the genetic code; phenotype is the expressed physical traits.

Front

Why did Mendel choose to experiment with pea plants?

Back

He wanted to study inheritance patterns due to their traits and fast reproduction.

Front

What is the second step of meiosis?

Back

Prophase I.

Front

What is a sister chromatid?

Back

A sister chromatid is one of the two identical copies of a chromosome, formed after DNA replication.

Front

What is the importance of crossing over in meiosis?

Back

It increases genetic diversity in offspring.

Front

What is independent assortment in meiosis?

Back

The random distribution of maternal and paternal chromosomes into gametes, increasing genetic variation.

Front

Define meiosis.

Back

Meiosis is a type of cell division that reduces the chromosome number by half, producing four haploid cells.

Front

What are gametes?

Back

Gametes are reproductive cells (sperm and eggs) that carry half the genetic information of an organism.

Front

What is Mendel's Law of Segregation?

Back

The law states that allele pairs separate during gamete formation, and randomly unite at fertilization.

Front

What is Mendel's Law of Independent Assortment?

Back

The law states that genes for different traits are inherited independently of each other.
