Meiosis II produces 4 haploid daughter cells whereas meiosis I produces 2 diploid daughter cells.

. O Sister chromatids are scparated. The chromosome number per cell is the same. After telophase I of meiosis the chromosomal makeup of each daughter cell is.

In meiosis I chromosomes in a diploid cell resegregate producing four haploid daughter cells. Crossing over occurs during which phase of meiosis. Four daughter cells are formed Homologous chromosomes of a pair are separated from cach other.

DNA replication precedes the start of meiosis I. QUESTION 25 Which of the following happens during prophase I of meiosis. The statement is true for meiosis I only C.

Which of the following happens during meiosis 1. Conversely it can happen that homologous chromosomes do not remain attached. Each answer mey be not at al.

The two chromosomes of each bivalent separate and move to the opposite ends of the cells. Which of the following happens during meiosis I. Meiosis 1 Anaphase 1.

O recombination between non-sister chromatids of homologous chromosomes O recombination between sister chromatids of homologous chromosomes O recombination between non-sister chromatids of nonhomologous chromosomes O. The statement is true for mitosis only B. During prophase I homologous chromosomes pair and form synapses a step unique to meiosis.

The sister chromatids are attached to each other. An event of this type is called a non-disjunction. 58 The following question refers to the essential steps in meiosis described below.

28 Which of the following processes happens during meiosis I. In meiosis I homologous chromosomes separate while in meiosis II sister chromatids separate. If a cell of usually diploid species with 42 chromosomes per cell is triploid this cell would be expected to have which of the following.

Genetic recombination via crossing over may occur. Meiosis 1 Telophase 1. In meiosis I homologous chromosomes separate while in meiosis II sister chromatids separate.

Genetic recombination crossing over only occurs in meiosis I. Meiosis I involves the separation of homologous chromosomes while meiosis II involves the separation of sister chromatids. Meiosis 1 Metaphase 1.

C Sister chromatids are separated. Synapsis is the pairing of two chromosomes that occurs during meiosis. During prophase I homologous chromosomes pair and form synapses a step unique to meiosis.

The statement is true for meiosis II only D. Which of the following events happens at the conclusion of meiosis I. Separation of the homologs.

DNA replication precedes the start of meiosis I. Meiosis which reduces the chromosome number by half. D Sister chromatids are separated.

Metaphase Use the following key to answer the following questions. Meiosis is a specialized cell division which occurs in germ cells and produces haploid gametes. D prophase II e.

Chromosomal crossover or crossing over is the exchange of genetic material during sexual reproduction between two homologous chromosomes non. What happens if an organism does not carry out meiosis. D Four daughter cells are formed.

Separation of sister chromatids 4. The meiosis is characterised by pairing of homologous chromosomes exchange of segments between homologous chromosomes and reduction in chromosome number to half. A Homologous chromosomes of a pair are separated from each other.

Each tetrad is composed of four chromatids. No uncoupling of the centromere 5. What happens during meiosis I.

Wsed once mone than once A. A triploid cell contains sets of chromosomes. The G2 phase precedes meiosis I or mitosis but does no precede meiosis II.

It is a part of gamete production in both males sperm and females eggs A. It is this step in meiosis that generates genetic diversity. It allows matching-up of homologous pairs prior to their segregation and possible chromosomal crossover.

DNA replication precedes the start of meiosis I. In meiosis I chromosomes in a diploid cell resegregate producing four haploid daughter cells. Haploid the chromosomes are each composed of 2 chromatids.

So the correct answer is Pairing of homologous chromosomes. The correct number of chromosomes is maintained during sexual reproduction by. Genetic recombination crossing over only occurs in meiosis I.

If meiosis did not occur in sexually reproducing organisms the chromosome number would be double in each generation. Synapsis occurs a pair of homologous chromosomes lines up closely together and a tetrad is formed. It is this step in meiosis that generates genetic diversity.

63 chromosomes in 21 sets of 3. A Four daughter cells are formed. In the Meiosis I cell division a cell divides to produce two diploid cells with exactly the same amount of DNA as that of original parent cell.

Meiosis II produces 4 haploid daughter cells whereas meiosis I produces 2 diploid daughter cells. It may happen that a pair of homologous chromosomes does not cleave at meiosis I or that the sister chromatids do not separate during meiosis II or during mitosis. B Homologous chromosomes of a pair are separated from each other.

Formation of four new nuclei each with half the chromosomes present in the parental nucleus 2. In prophase I of meiosis the following events occur. B The chromosome number per cell is conserved.

The bivalents align at the equatorial plate and microtubules from the opposite poles attach to the pairs of homologous chromosomes. A phase during the first division meiosis I where the tetrads attach to the spindle and align at the spindle equator A. After Meiosis II four haploid cells are produces with half the amount of DNA as that of original parent cell.

Chromosomes condense and attach to the nuclear envelope. It is this step in meiosis that generates genetic diversity. Alignment of homologous chromosomes at the metaphase plate 3.

What happens in meiosis I. Most humans somatic body cells are. Biology questions and answers.

In meiosis I chromosomes in a diploid cell resegregate producing four haploid daughter cells. However the number of chromosomes is reduced to by half at the end of meiosis I.
