Cells
Products of meiosis.
What are gametes?
A cell with 2 sets of chromosomes.
What is a diploid cell?
The two main parts of meiosis.
What are Meiosis I and Meiosis II?
This is the number of chromosomes present in a germ cell.
What are 46?
One of these is NOT part of the chromosome: spindle fiber, centromere, chromatid
What is the spindle fiber?
The product of oogenesis.
What is one ovum and 3 polar bodies?
A zygote is this
What is diploid?
The 8 stages of meiosis
What are Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II, Telophase II?
This is the number of chromosomes present in each human cell by the end of Meiosis I.
What is 23?
What is the difference between a pair of homologous chromosomes?
What is they don't necessarily have the same versions of each gene?
The cell that donates most of the cytoplasm to the zygote.
What is the ovum?
A sperm cell is this.
What is haploid?
This is the cytoplasmic division of a cell that happens once in mitosis and twice in meiosis.
What is cytokinesis?
This is the number AND type of cells made at the end of Meiosis 2.
What are 4 genetically unique haploid cells (some become gametes)?
A difference between the products of oogenesis and spermatogenesis.
What is the number of gamtes produced (4 sperm cells vs 1 ovum)?
Product of fertilization.
What is a zygote?
A germ cell is this.
What is diploid?
The stage where homologous chromosomes are separated.
What is anaphase I?
If a diploid cell with 24 chromosomes undergoes meiosis, this is the number of chromosomes in each daughter cell.
What is 12?
The similarity between mitosis and meiosis II
What is both separate sister chromatids?
Cells that go through chromosomal reduction.
What are germ cells?
A cell with half the number of chromosomes.
What is a haploid cell?
This must happen before Meiosis begins to enable two identical sister chromatids in each chromosome.
What is DNA replication?
The number of chromosomes humans get from each parent.
What is 23 chromosomes?
The difference between Anaphase I and Anaphase II.
What is Anaphase I separates homologous chromosomes, and Anaphase II separates the sister chromosomes?
