Meiosis and Genetic Variation

Meiosis produces daughter cells that are:

• genetically identical

• genetically different

• zygotes

• germ cells

*Two copies of chromosomes that share similar genes, but may have different alleles are called:

• sister chromatids

• Chromie Homies

• Replicated chromosomes

• homologous chromosomes

Germ cells (cells that make egg and sperm cells) go through:

• mitosis

• meiosis

• DNA replication

An organism has 36 chromosomes in its genome (all the chromosomes it has). What would be the correct diploid number?

• 36

• 72

• 18

• 2

An organism has 36 chromosomes in its genome (all the chromosomes it has). What would be the correct haploid number?

• 36

• 72

• 18

• 2

When does crossing over occur?

• Mitosis

• Meiosis

• Prophase II

• Anaphase I

All of the following create genetic variation EXCEPT..

• Mutations

• DNA Replication

• Law of Independent Assortment

• Crossing Over

Fertilization...

• happens randomly

• is controlled by the sperm cells

• is controlled by the egg cells

• results in individuals have identical traits to their parents

What describes the physical appearance of a trait?

• allele
• genotype
• phenotype
• karyotype

The genetic makeup of an organism or what represents the letters in a Dihybrid Cross

• allele
• genotype
• phenotype
• karyotype
