What is a homologous pair of chromosomes in meiosis?
A picture of the chromosomes is called a
diagram
karyotype
chromosome map
stage picture
The medical procedure where a doctor draws fetal fluid from a pregnant mother is called
an amniocentisis
a draw
an incision draw
a fetal monitoring draw
Sex chromosomes that identify a female are
X
Y
XX
XY
Sex chromosomes that identify a male are
X

Why must DNA replication happen?
to provide each cell with DNA
to provide the cell with organelles
it doesn't have to happen
to provide each cell with 1/2 the number of chromosomes
What is important about Prophase 1 in meiosis?
this is where genetic variability does not happen
this is where crossing over happens that increases genetic variability
the chromosomes pair
the chromosomes separate
What is Independent Assortment?
the mixing of the chromosomes
this only happens in mitosis
the separating of chromosomes that have exchanged genetic information, making each one genetically different
the shuffling of traits
Why is Anaphase 1 important in meiosis?
If chromosomes don't separate correctly, non disjunction can happen
independent assortment happens
This is the stage where segregation of chromosomes happen
crossing over happens here
How are mitosis and meiosis alike?
they both have the divisions PMAT
they both start with a 2n cell
they both have DNA replication in the S phase of Interphase
they both make cells that are genetically the same
