Question

Consider each of the following statements.

In meiosis, the chromosomal material doubles during the last premeiotic interphase.

The greater the number of chromosome pairs, the greater is the effect of meiosis in producing genetically distinct gametes.

The diploid number of chromosomes is half the haploid number.

A cell that will not divide again remains in the G2 stage of interphase.

The correct sequence of events during meiosis is: synapsis ? dyad formation ? chiasma formation

An organism with n = 3 has 1 chance in 8 of producing a gamete with all maternally derived chromosomes.

An organism with n = 3 can produce 8 different kinds of gametes in relation to combinations of maternal and paternal chromosomes.

Separation of sister chromatids occurs during anaphase I of meiosis and is the physical basis for the law of independent assortment.

A single diploid cell that undergoes meiosis in the male testis will produce 4 genetically different gametes if crossing-over is ignored.

The independent alignment of different tetrads at metaphase I of meiosis is the physical basis of the law of independent assortment.

If a diploid cell has 20 pairs of chromosomes, there will be 10 tetrads during prophase I of meiosis.

If a diploid cell has 20 pairs of chromosomes, there will be 20 bivalents during prophase I of meiosis.

If a diploid cell has 20 pairs of chromosomes, there will be 80 chromatids present during metaphase of mitosis.

If a diploid cell has 20 pairs of chromosmes, the organism can make 202 types of gametes if crossing-over is ignored.

Segregation of sister chromatids occurs during anaphase I of meiosis and is the physical basis of the law of segregation.

The independent movement of individual homologous chromosomes at metaphase I of meiosis is the physical basis for the law of independent assortment.

For an individual with a diploid number of 30 chromosomes, there will be 60 chromatids at metaphase I of meiosis.

For an individual with a diploid number of 30 chromosomes, there will be 15 tetrads at metaphase II of meiosis

Thank you for any help!

According to chegg rules, we can answer only the first 4 subparts. So I will answer the first 4.

In meiosis, the chromosomal material doubles during the last premeiotic interphase.- False.

The greater the number of chromosome pairs, the greater is the effect of meiosis in producing genetically distinct gametes.- True

The diploid number of chromosomes is half the haploid number. False. The haploid is n and the diploid number is 2n.

A cell that will not divide again remains in the G2 stage of interphase. False. It will remain in G1 phase
