mitosis
crossing over
independent assortment
mutations
A. What does the picture below show?
B. Why is this important?
A. crossing over
B. increases variation/diversity
A. crossing over
B. decreases variation/diversity
A. nondisjunction
B. increases variation/diversity
A. nondisjunction
B. decreases variation/diversity
An advantage of sexual reproduction is that
many offspring are produced in a short time
it increases genetic diversity
production of gametes requires energy
organisms remain stable in a changing environment
How does diploid differ from haploid?
Diploid is having 1 set of chromosomes, 23 chromosomes total
Haploid is having 1 set of chromosomes, 46 chromosomes total
Hapolid is having 2 sets of chromosomes, 23 chromosomes total
Diploid is having 2 sets of chromosomes 46 chromosomes total
What does homologous chromosomes mean?
having 46 chromosomes (23 pairs)
programmed cell death
Pair of chromosomes that have the same information
Pair of chromosomes that have different information
What is crossing-over?
Moving on from the living
Exchanging genetic material during prophase 1
A type of mutation where information is moved around
The process of rearranging the chromosomes to prepare for division
Mitosis occurs in a
sex cell
somatic cell
gametes
diverse, identical
identical, diverse/different
Prophase
Metaphase
Anaphase
Telophase
Interphase

(a) creates somatic cells and (b) creates haploid cells
Translate the DNA strand below to form a protein.
(Your answer will be only the amino acides that corralate to the mRNA strand you create from the DNA strand). You will have to use the amino chart to determine the correct amino acid
