How does anaphase II differ from anaphase I?

Anaphase 1 and anaphase 2 are two phases in the meiotic division of cells which produces gametes during the sexual reproduction. The main difference between anaphase 1 and 2 is that homologous chromosomes are separated during anaphase 1 whereas sister chromatids are separated during anaphase 2.

How does anaphase II differ from anaphase I quizlet?

In meiosis, what is the difference between Anaphase I and Anaphase II? In Anaphase 1 , the homologous (same) chromosomes separate to either side of the cell, and the centromere is whole. In Anaphase 2, the sister chromatids separate, and the centromere is split, which causes the chromatids to separate.

What are the differences between anaphase I & anaphase of mitosis?

In anaphase 1 in meiosis, homologous pairs are separated but sister chromatids stay joined together. In anaphase 1 of mitosis the sister chromatids do separate.

Which of the following is not a difference between anaphase I and anaphase II of meiosis?

Which of the following is NOT a difference between anaphase I and anaphase II? … Anaphase I occurs in a haploid cell while anaphase II occurs in a diploid cell. It could be said that males are able to provide gametes with more genetic diversity than females for reproduction.

What is the difference between sister chromatids before and after anaphase two?

The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase II, the chromosomes line up individually along the metaphase plate. In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell.

What do you notice about the size of the two resulting cells?

What do you notice about the size of the two resulting cells? They are different sizes, one is bigger than the other. Result is 2 identical cells with 46 chromosomes.

What are the three differences between mitosis and meiosis?

The differences between mitosis and meiosis

Mitosis Meiosis
• Maintenance of chromosome number (diploid) • Reduction/halving of chromosomes (haploid)
• Takes place in somatic cells/growth • Occurs in reproductive cells/gonads/produces gametes
• No crossing over/no variations • Crossing over takes place/variation occurs

What are the main differences between mitosis and meiosis?

Mitosis involves the division of body cells, while meiosis involves the division of sex cells. The division of a cell occurs once in mitosis but twice in meiosis. Two daughter cells are produced after mitosis and cytoplasmic division, while four daughter cells are produced after meiosis.

How can you tell the difference between meiosis 1 and 2?

In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas Meiosis I produces 2 diploid daughter cells.

What is the difference between Zygotene and Pachytene?

Pachytene is the phase in which exchange of genetic material or crossing over takes place between non-sister chromatids of bivalents. Zygotene, on the other hand, is the phase in which the pairing of homologous chromosomes takes place forming synaptonemal complexes.

What is the difference between homologous chromosomes and Tetrads?

Homologous chromosomes are the pairs of chromosomes you have in (virtually) all of your cells. … So effectively each chromosome is made of two sister chromatids attached in the middle (looking like an X). A tetrad is when the homologous chromosomes which have already copied their DNA pair up.

What is the major difference between metaphase and metaphase I?

What is the major difference between metaphase I and metaphase II? Metaphase I pairs homologous chromosomes and in metaphase II they are not paired. … Meiosis I begins with diploid cells, and homologous chromosomes separate in this stage.

What is the difference between homologous chromosomes and sister chromatids quizlet?

Homologous chromosomes contain the same gene loci but may have different alleles of a particular gene. Sister chromatids are identical copies of each other produced during DNA replication.

What is the difference between sister chromatids and homologous chromosomes?

Sister chromatids are used in cell division, like in cell replacement, whereas homologous chromosomes are used in reproductive division, like making a new person. … On the other hand, a pair of homologous chromosomes consists of two non-identical copies of a chromosome, one from each parent.
