When genes are placed in the reverse order on a
chromosome, this is called

An inversion.

13
When does crossing over occur and why?
10
Meiosis
14
Prophase 1 when homologous chromosomes undergo
synapsis and form a tetrad for genetic
diversity in gametes

Meiosis
15
What are the products of meiosis?
20
Meiosis
16
4 genetically different haploid cellsSperm/egg
cells (gametes)
20
Meiosis
17
Why do homologous chromosomes pair up during
prophase 1 of meiosis but never in mitosis?
30
Meiosis
18
To reduce the number of chromosomes (stays the
same in mitosis)to enable crossing over to
occur (stays the same in mitosis)
30
Meiosis
19
What is the law of segregation?
40
Meiosis
20
separation of chromosomes during anaphase 1 of
meiosis.ensures gametes only have one copy of
each allele
40
Meiosis
21
What is the law of independent assortment?
50
Meiosis
22
50
Meiosis
Chromosomes with different alleles sort
independently along the metaphase plate of
meiosis 1.
23
10 Meiosis
What term is used to describe chromosomes that
carry the same genes, just different versions of
those genes?
24
Homologous Chromosomes
10
Meiosis
25
When do homologous chromosomes pair up? What
happens as a results?
20
Meiosis
26
Prophase 1- synapsis occurs, a tetrad forms,
enabling crossing over.

27
What is required before meiosis can occur?
30
Meiosis
28

Meiosis
DNA replication in a diploid cell.

Anaphase 1 homologous chromosomes separate
into individual chromosomes (sister
chromatids) cell is now haploid

A cat has a diploid number of 38. What
would the number of chromosomes be in a cell in
telophase 1 of meiosis in this cat? What would it
look like?What would the number of chromatids be
in a cell in telophase 2 of meiosis in this cat?
What would it look like?

the offspring are all brown. What are the

Genetics 1
Since each pair of alleles segregate separately
from other pairs of alleles, Mendel created

40
Genetics 1
The Law of Independent Assortment supported by
homologous chromosome random sorting during
metaphase 1 of meiosis.
41
50
Genetics 1
Because alleles separate when homologous
chromosomes split in anaphase 1 of meiosis, this
supports Mendels

(called a test cross)
