Meiosis and Mendelian Genetics

Meiosis Phases

100

What separates in Meiosis Anaphase 1?

Homologous chromosomes

200

What is the organelle called that is responsible for the formation of spindle microtubules? 

Centrosome

300

What phase includes cytokinesis?

Telophase

400

What phase does crossing over happen?

Prophase 1

500

What is the difference between meiosis and mitosis? What is the final outcome? How are each useful?

Meiosis makes gametes and has 2 division; mitosis makes body cells and has 1 division. Mitosis allows for the body to recover from damage while meiosis allows for the formation of babies.

Determining Genotypes or Phenotypes

100

How many offsprings look like the parents if the parent genotypes are Aa Aa?

3/4

200

What is something that experiences codominance that is in the notes? (hint: made in bone marrow)

Blood types!! 

300

If there is incomplete dominance, what will the offspring of a E^bE^b blue elephant and a E^yE^y yellow elephant?

A green elephant!

400

What would happen if a codominant allele was inherited by an offspring that coded for green arms and another allele that coded for blue arms?

Their arms would have blue and green splotches. 

500

What is the phenotypic ratio of a dihybrid cross?

9:3:3:1

Mendelian Vocab

What does complete dominance refer to?

Dominant vs. Recessive

200

Define Epistasis

When the expression of a gene at one locus alters the phenotypic expression of a gene at a second locus. 

300

What is a testcross?

The breeding of a mysterious genotyped individual with a homozygous recessive individual. 

400

Define law of independent assortment.

each pair of alleles segregates independently of any other pair of alleles during gamete formation. 

500

Define pleiotropy

When a gene has multiple phenotypic effects. Like sickle cell effecting blindness, liver failure, and heart attack.

MISC

100

What are carriers?

Heterozygotes. Individuals who carry the recessive allele but display the dominant allele.

200

What plant did Mendel use to discover the basic principles of heredity?

Pea Plants

300

What connect two sister chromatids together and is the site where the spindle fibers grab onto during metaphase?

Kinetochore

400

What are alternate versions of a gene called?

alleles

500

What disease is inherited dominantly that leads to the degeneration of the nervous system?

Huntington's disease
