Mitosis
These are chromosomes that have genes for the same traits in the same locations.
What are Homologous Chromosomes?
An exchange of parts of NON-sister chromatids.
What is crossing-over?
Those with an extra copy of Chromosome 21.
What is down syndrome?
The offspring of this cross is:
50% heterozygous
50% homozygous recessive
Aa x aa
The study of the genome.
What is genomics?
In somatic cells.
Where does mitosis occur?
Name the stage.
The cell is now haploid. The spindle fibers attach to chromosomes at their centromere and they begin to move to the metaphase plate.
What is prophase II?
In gametes.
Where does meiosis occur?
Two-Part:
This inheritance pattern results in an in-between trait.
This inheritance pattern results in co-expression.
What is incomplete dominance and codominance?
Name the stage.
The centromeres of the sister chromatids separate becoming independent chromosomes.
What is anaphase II?
Name the type of inheritance.
Generation I: no family members express the recessive trait
Generation II (offspring of GI): 3 children (boy, boy, girl), 1 child (Boy 2) has the trait
Generation III (offspring of Boy 1): 2 children, 1 child has the trait
What is autosomal recessive?
In telophase, this deepens and divides the cell into two.
What is the cleavage furrow?
This is a blood clotting disorder that spread among the royal families of Europe.
What is hemophilia?
Draw and explain the entire process of mitosis.
Yes, you will have several questions related to mitosis!
Explain the entire process of meiosis.
Yes, you need to know this!
Draw a pedigree.
Generation 1: Mom and Dad do not express
Generation 2: 4 children (3 boys and 1 girl), 2 boys have the recessive trait
Generation 3:
Boy 1 (with trait) - married to normal wife, 2 children (boys) without trait
Girl 1 - married to normal man, 2 children (boys) with trait), 1 daughter without trait
