Meiosis vs Mitosis
How many cells exist at the end of Meiosis
4 Cells
How many phases are in Meiosis
8
Where are genes stored in the cell?
Chromosomes
Also accepted: Nucleus
Who came up with the concept of heredity?
Gregor Mendel
Where do sister chromatids join together?
True or False:
There are the same amount of phases in Meiosis as Mitosis
False
There are four phases in Mitosis, and eight phases in Meiosis.
How many examples of cell division occur in Meiosis?
Three (one in Meiosis I, then both of the new cells replicate)
What cell is formed when gametes fuse together?
Zygotes
What causes genes to be inherited separately?
Independent assortment
What kind of cells does Meiosis produce?
Gametes
True or false:
Meiosis I and Mitosis have the same phases.
True
Anaphase I
Anaphase II
How many chromosome copies are in Haploid cells?
There is 1 copy.
When you cross two heterozygous genotypes for a single trait, what is the chance of the offspring showing the recessive trait?
25% chance
What does Haploid mean
One copy of chromosomes
What type of cell division is asexual?
Mitosis
True or False:
During Meiosis, the cells undergo chromosome replication twice.
False, meiosis II does not involve chromosome replication.
How many chromosome copies are in Diploid cells?
There are 2 copies.
Why are some traits nearly always inherited together?
Gene Linkage
What law says that alleles for a trait are passed down independently from alleles for another trait?
Independent Assortment
What feature of Meiosis causes it to create unique daughter cells?
Crossing Over
In which example of Prophase does crossing over occur?
Prophase I
True or False:
The number of chromosome copies in the gametes and zygotes are the same.
False.
Gametes are haploids (1) and zygotes are diploids (2).
True or False:
Linked genes never separate, and are always inherited together.
False.
It is rare, but possible for genes to separate.
Which law says that alleles separate from each other?
Law of Segregation
