Mitosis
This is the stage before mitosis, when cells grow and synthesize
What is interphase?
These(this) are(is) the number(s) of rounds of interphase and cytokinesis for all of meiosis
What is one and two?
Crossing-over occurs at this stage of meiosis
What is prophase I?
This is the total genetic component of an organism
What is genome?
True or false: Regardless whether nondisjunction occurs during meiosis I or meiosis II, the resulting daughter cells will have the same chromosome counts
What is false?
The acronym that tells the stages of mitosis
What is PMAT?
During anaphase I, these are pulled to opposite poles of the cell
What are homologous chromosomes?
Pigs grow from a fertilized embryo to an adult size of 200 kg mainly through a biological process known as this
What is mitosis?
This term refers to the presence of two copies of each chromosome
What is diploid?
This characterizes a dicentric chromosome
What are two centromeres?
This is the stage of mitosis when chromosomes are most condensed
What is metaphase?
This mechanism is important for creating new combinations of genes via the exchange of genetic material between chromatids of homologous chromosomes
What is crossing over?
A cell with a total of 6 chromosomes (2N = 6) will have this many individual chromatids formed at the end of the interphase prior to mitosis.
What is 12?
This is when the centromere is located near one end of the chromosome
What is acrocentric?
These are energy-producing organelles that contain DNA
What are mitochondria?
During anaphase, these are pulled to opposite poles of the cell
What are sister chromatids?
This is when oogenesis is arrested in meiosis
What is meiosis I/prophase I?
A diploid cell with a total of 10 chromosomes (2N = 10) will have this many individual chromatids aligned on the metaphase plate during meiosis I
This is nuclear division
What is karyokinesis
This is an aneuploid condition that results from three copies of chromosome 21
What is Down Syndrome?
The number of chromosomes and ploidy at the conclusion of mitosis in humans
What is 46 and diploid?
The number of chromosomes at the conclusion of meiosis in humans
What is 23 and haploid?
Sister chromatids are formed initially in this phase of a cell cycle, and begin to be separated from each other in this phase
What are interphase and anaphase?
This is a cross between true-breeding parents that differ in two traits
What is a dihybrid cross?
An animal has 22 chromosomes (2N=22), this is the number of chromosomes it would have if it has a triploid stage
what is 33?
