Meiosis and Genetics Review

Match the following vocabulary words with their definitions

• The total physical appearance for an individual.

• Heredity

• The Scientific study of heredity

• Genetics

• The specific genetic make up or "code" for an individual.

• Genotype

• The process in which characteristics are passed down from parents to offspring.

• Phenotype

• An organism's characteristics.

• Trait

Having a Widow's Peak is dominant (W) over not having one (w). If parent A (WW) and parent B (ww) have a child, what is the likelihood that--

• 100%

• The child will have a widow's peak

• 0%

• The genotype of these children

• Ww

• The child will not have a widow's peak

This type of inheritance pattern is a MIXTURE of two traits. This is known as ---

• incomplete dominance.

• codominance

Which of the following genotypes code for the blood type AB?

• I^A I^A and I^A I^B

• I^A I^B only

• I^A I^B and I^B i

• ii only

What are the key words to think about for codominant traits?

Choose all that apply.

• Blending of colors

• Stripes

• Spots

What trait is being shown?

• Incomplete

• Codominance

Match the following for mitosis and meiosis.

• Anaphase 1 of Meiosis

• Homologous Chromosomes pulled apart & Independent assortment

• Mitosis & Meiosis

• makes 2 identical cells

• Meiosis

• PMAT happens once or twice

• Anaphase 2 of Meiosis

• makes 4 genetically different cells

• Mitosis

• Sister Chromatids (already crossed over) pull apart

This image shows chromosomes during Prophase 1. Which of the following correctly describes the process shown?

• segregation of sister chromatids
• condensation and segregation of alleles
• mutationin which the DNA content of the gene is altered
• crossing - over in which alleles are exchanged

• Telophase I
• Metaphase II
• Telophase II
• Anaphase I

Name the phase:

• Telophase I

• Metaphase I
