Stages
The division of the cytoplasm
cytokinesis
A structure on the chromosome that holds a pair of chromatids together during replication
What is a centromere?
A type of cell division that reduces the number of chromosomes
What is meiosis?
Reproduction that involves a single parent
What is asexual reproduction?
sperm or egg cells
What are gametes?
The first phase of meiosis I
What is prophase I?
A double-stranded chromosome following replication attached by a centromere
What is a chromatid?
The chromosomes that make up a pair , one chromosome from each parent
What are homologous chromosomes?
One method of asexual reproduction, where a parent cell splits into two identical daughter cells
What is binary fission?
a section of DNA that influences one or more hereditary traits in an individual
What is a gene?
The period of normal growth and existence of cell
What is interphase?
A condition where non-sister chromatid of homologous chromosomes exchange genes
What is crossing over?
An alternative form of a single gene
What are alleles?
The process in which two gametes unite
What is fertilization?
chromosomes that are similar in size, shape, and genes
What is a homolog?
The phase in which 4 new haploid cell are formed
What is telophase II?
The process of development of haploid female gametes
What is oogenesis?
A cell that contains 2N number of chromosomes
What is a diploid?
One method of asexual reproduction, when the parent breaks into pieces and each fragment develops into a new organism
What is fragmentation?
replicated homologous chromosomes that are joined together (4 chromatids from 2 homologous chromosomes)
What is a tetrad?
The different phases of meiosis I in order
What is Prophase 1, Metaphase 1, Anaphase 1, Telophase 1, and Interkinesis?
One of three small cells produced during oogenesis
What is a polar body?
An organism with two different alleles for a particular trait
What is heterozygous?
When a multinucleated cell can divide to form more than one daughter cell
What is multiple fission?
the result of crossing over
What are recombinant chromosomes?
