binary fission
Prokaryotes reproduce by
binary fission only occurs in single celled organisms
How are binary fission and mitosis different?
asexual reproduction
Which type of reproduction produces genetically identical offspring?
sexual reproduction
Which type of reproduction produces genetically diverse offspring?
Fragmentation
An organism that breaks into pieces to reproduce is reproducing by what type of asexual reproduction?
Vegetative reproduction
Budding
Fragmentation
What are the three types of asexual mitotic reproduction?
somatic cells
Body cells are also called...
46
How many chromosomes are in human cell?
23
How many chromosomes are in a human gamete?
A chromosome that is not a sex chromosome
What is an autosome?
A single cell produces haploid gametes
Describe meiosis
chromosomes that contain the same genes, BUT ARE NOT GENETICALLY IDENTICAL
What are homologous chromosomes?
The production of gametes
What is gametogenesis?
22 autosomes and Either an X or Y chromosome
What chromosomes do humans get from their father?
22 autosomes and an X chromosome
What chromosomes do humans get from their mother?
Meiosis
What process is this?
binary fission
What process is this?
Crossing over
How does sexual reproduction contribute to genetic diversity?
Reproduction occurs quickly
What is an advantage to asexual reproduction?
two genetically identical daughter cells
In asexual reproduction, one parent cell produces...
Sex cells
(sperm and egg)
What are gametes?
