- On rare occasions, an organism may have three copies of achromosome and therefore has three copies of the genes on thatchromosome (instead of the usual number of two copies). Forsuch a rare organism, the alleles for each gene usually segregateso that a gamete will contain one or two copies of the gene. Let’ssuppose that a rare pea plant has three copies of the chromosomethat carries the height gene. Its genotype is TTt. The plant is alsoheterozygous for the seed color gene, Yy, which is found on adifferent chromosome. With regard to both genes, how manytypes of gametes can this plant make, and in what proportions?(Assume that it is equally likely that a gamete will contain oneor two copies of the height gene.)in the experiment of following chromosomal dna mvement througgh meiosis, why. do you use non-sister chromatids to demobstrate crossing over? what combinatiobns of alleles could result from a crossover between BD and bd chromosomes? Identify two ways that meiosis contributes to genetic recombination. Why is it necessary to reduce the number of chromosomes in gametes, but not in other cell?Somatic cells in organisms of a particular diploidplant species normally have 14 chromosomes. Thechromosomes in the gametes are numbered from 1through 7. Rarely, zygotes are formed that containmore or fewer than 14 chromosomes. For each of thezygotes below, (i) state whether the chromosomecomplement is euploid or aneuploid; (ii) provideterms that describe the individual’s genetic makeupas accurately as possible; and (iii) state whether ornot the individual will likely develop through theembryonic stages to make an adult plant, and if so,whether or not this plant will be fertile.a. 11 22 33 44 5 66 77b. 111 22 33 44 555 66 77c. 111 222 333 444 555 666 777d. 1111 2222 3333 4444 5555 6666 7777
- Can you think of anything that would prevent meiosisfrom occurring in an organism whose genome isalways haploid?What is the corect order of these meiotic events? A Segregation of homologous chromosomes to opposite poles 8 Segregation of sister chromatids to opponite poles. CAignment of homologous pairs on the midplate of thve cell. D Pairing and synapsis of homologous chromosomes. E Condensation of chromosomes in a diploid nucleus. CDEAB O DCERA O EDCBA O EDCAB O DCAREIs it more indicated for ageneticist desiring to map theX chromosome of the motherof a given family (theresearcher does not haveaccess to her DNA, only accessto the genetic material of theoffspring) to analyze thechromosomes of herdaughters or of her sons?
- A diploid species has four chromosomes per set for a total of eightchromosomes in its somatic cells. Draw such a cell as it wouldlook in late prophase of meiosis II and prophase of mitosis. Discuss how prophase of meiosis II and prophase of mitosis differfrom each other, and explain how the difference originates.In the moss Polytrichum commune, the haploidchromosome number is 7. A haploid male gametefuses with a haploid female gamete to form a diploid cell that divides and develops into the multicellular sporophyte. Cells of the sporophyte thenundergo meiosis to produce haploid cells calledspores. What is the probability that an individualspore will contain a set of chromosomes all ofwhich came from the male gamete?How does the attachment of kinetochore microtubules to thekinetochore differ in metaphase of meiosis I compared tometaphase of mitosis? Discuss what you think would happenif a sister chromatid was not attached to a kinetochoremicrotubule
- After telophase Il of meiosis, the chromosomal makeup of each daughter cell is: Practia diploid, and the chromosomes are each composed of a single chromatid. O diploid, and the chromosomes are each composed of two chromatids. O haploid, and the chromosomes are each composed of a single chromatid. O haploid, and the chromosomes are each composed of two chromatids.A person is born with one X chromosome, zero Y chromosomes,trisomy 21, and two copies of the other chromosomes. How manychromosomes does this person have altogether? Explain whetherthis person is euploid or aneuploid.Suppose that meiosis occurs in the transient diploid stageof the cycle of a haploid organism of chromosome number n. What is the probability that an individual haploidcell resulting from the meiotic division will have a complete parental set of centromeres (that is, a set all fromone parent or all from the other parent)?
