Meiosis
Cell division cycle that has the following stages: prophase I, Metaphase I, Anaphase I, and Telophase I.
What is Meiosis I?
Cell Division process that has the following phases: Prophase, Prometaphase, Metaphase, Anaphase, and Telophase.
What is Mitosis?
The random way each pair of homologous chromosomes lines up at the metaphase plate suring meiosis I.
What is Independent Assortment?
Reproduction that allows individuals to transmit half of their genes to each offspring.
What is Sexual Reproduction?
The cycle made up of the following phases: G1, S, G2, Mitosis, and Cytokinesis.
What are the 5 phases of the cell cycle?
Cell Division Cycle that has the following stages: prophase II, Metaphase II, Anaphase II, and Telophase II.
What is Meiosis II?
Asexual reproduction occurs during ______.
What is Mitosis
Cycle in which sister chromatids separate from each other.
What is mitosis and Meiosis II?
Mendel crossed yellow-seeded and green-seeded pea plants and allowed self-pollination to make an F2 generation. Results were: 6022 yellow and 2001 green (8023 total). The green seed is _____ allele.
What is the recessive allele?
An enzyme that attaches phosphate groups to other proteins.
What is Cyclin-dependent kinase (Cdk)?
Homologous chromosomes of a pair are separated from each other.
What occurs at the conclusion of Meiosis I?
The phase the cell enters when MPF (mitosis-promoting factor) is introduced into immature frog oocytes that are arrested in G2.
What is Mitosis or the mitotic phase (M phase)?
This chromosome carries information for the same traits.
What is a homologous chromosome?
There are 7 different traits that Mendel studied in plants.The genetic term for an observable trait is known as _____.
What is a phenotype?
If a cell has accumulated DNA damage during the S phase, it is unlikely to ___________.
What is pass the G2 checkpoint?
The phase of cell division in which Mendel observed the segregation of alleles in gamete formation.
What is Anaphase I of meiosis
A cell shows the beginning of a cell plate across the middle of a cell and nuclei forming on either side of the cell plate.
What occurs in a plant cell in the process of cytokenisis?
The number of chromosomes found in the ovum of a roundworm in which the somatic cells have 4 individual chromosomes per cell.
What is 2 chromosomes?
When crossing an organism that is homozygous recessive for a single trait with a heterozygote there is a 50% chance of this phenotype.
What is an offspring with the homozygous recessive phenotype?
Proteins that are involved in the regulation of the cell cycle and that show fluctuations in concentration during the cell cycle are called ___________.
What are cyclins?
The phase in which the synaptonemal complex disappears.
What is before metaphase of meiosis I?
The phase when centrioles begin moving apart in the animal cell.
What is prophase?
In eukaryotic cells, chromatin is composed of _________.
What is DNA and proteins?
The common source of the extra chromosome 21 in an individual with Down syndrome.
What is nondisjunction in the mother?
The first gap in the cell cycle (G1) corresponds to _________.
What is normal growth and cell function?
