During alternation of generations, cells reproduce by both meiosis and mitosis
In alternation of generations, a diploid spore-forming cell gives rise to four haploid spores
To create new haploid cells during the haploid life cycle, the zygote undergoes meiosis
Cellular in not a type of sexual life cycle
The simplest and most primitive method of reproduction is asexual
Budding is an example of asexual reproduction
Hydras reproduce by budding
Types of asexual reproduction include budding, fragmentation, and fission
Fertilization is not a type of asexual reproduction
The process of producing offspring is called reproduction and can be asexual or sexual
The more common name for an ovum is a egg
During cytokinesis in the female, the cytoplasm divides unequally
Cytokinesis does not provide new genetic combinations
Crossing-over occurs during prophase 1
The exchange of segments of DNA between the members of a pair of chromosomes acts as a
source of variations within a species
Separation of homologous occurs during meiosis 1
The difference between anaphase of mitosis and anaphase 1 of meiosis is that chromotids do
not separate at the centromere in anaphase 1
When crossing-over takes place, chromosomes exchange corresponding segments of DNA
The stage of meiosis during which homologous line up along the equator of the cell is called
metaphase 1
Fertilization of the haploid sperm and egg results in the restoration of the diploid number of
chromosomes in the zygote
After a new membrane forms during telophase of meiosis, the cytoplasm divides, resulting in
two cells
The cells resulting from meiosis in either males or females are called gamates
The process called meiosis guarantees that the number of chromosomes in gametes is half the
number of chromosomes in body cells
A reciprocal exchange of corresponding segments of DNA is called crossing-over
The four haploid cells formed in the male at the end of meiosis 2 develop a tail and are called
sperm
An individual produced by asexual reproduction that is genetically identical to its parent is called
a(n) clone
The separation of a parent into two or more individuals of about equal size is called fission
The process in which sperm and egg cells join is called fertilization
A spore is a haploid reproductive cell produced by meiosis
The entire span in life of an organism from one generation to the next is called a(n) life cycle
The diploid phase in the life cycle of plants is called the sporophyte
