192 After meiosis Il is complete, how many chromosomes are in each daughter cell? How does
this compare to the number of chromosomes in your meiosis daughter cells? How does that
number compare to the number of chromosomes in your par- ent cell that started meiosis? Are
there homologous pairs of chromosomes in each of the four daughter cells? Are your daughter
cells genetically identical?Explain your answer. Activity 8B Crossing Over During Meiosis
Materials for group of 4) Pop bead chromosomes (from Activity 8A) Cell division poster
Procedure During prophase I of meiosis, non-sister chromatids of a pair of homologous chrom
somes may exchange pieces of genetic material from one homologue to the other. T event is
called crossing over, and it results in recombination of genetic informat in the daughter cells
(Figure 8.5). Restore the chromosomes to their original config tion, as shown in Figure 7.20.
Repeat the meiosis simulation procedures, except thist simulate crossing over at prophase I. Do
this by exchanging the exact segments of non-sister chromatids of a single homologous pair.

Solution
Answer: After meiosis II is complete how many chromosomes are in each daughter cell? 23
chromosomes. How does this compare to number of chromosomes in your meiosis I daughter
cells? 23 chromosomes
(Since meiosis I is reduction division, at the end of meiosis I, the 46 chromosomes are halved to
23, i.e diploid sets of chromosomes, 23x2 (2n) get reduced to haploid sets 23(n). Meiosis II being
equational division the chromosome number remains same as in the daughter cells of Meiosis I,
i.e 23 which means haploid cells remain haploid in Meiosis II stage).
How does that number compare to the number of chromosomes in parent cell. The parent cell
that undergoes meiosis has the diploid set of chromosomes, 2n=46, which exist in the form of 23
pair of chromatids.
Are there homologous chromosomes in each of the four daughter cells? NO
Are daughter cells genetically identical? NO, the daughter cells produced in meiosis are not
genetically identical, since they result from seperation of homologous chromosomes and later
sister chromatids.
How many chromosomes in zygote? Zygote is formed as a result of fusion of haploid egg and
sperm, this makes zygote a diploid entity, and hence the total number of chromosomes in 2n
zygote are 46.
Are there homologous pair of chromosomes in zygote? YES. How many pairs of homologous
chromosomes are there in a zygote? There are 23pairs of homologous chromosomes in zygote.
Would the cell that has these chromosomes be diploid or haploid? Diploid. What is the diploid
