- For a species with a diploid number of 18, indicate how many chromosomes will be present in the somatic nuclei of individuals that are haploid, tetraploid, trisomic, and monosomic.For a species with a diploid number of 22, how many chromosomes will be present in the somatic nuclei of individuals that are haploid, tetraploid, trisomic, and monosomic.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
- Consider the true diploid plant cell (2n=4) below. The paternally derived blue chromosomesare of two types, metacentric and acrocentric. These chromosomes contain the same gene pattern andstructural features as the maternally derived purple chromosomes. Consider two genes A and B whichare found on the metacentric and acrocentric chromosome pairs, respectively. Assume the father passedon A and B alleles, and the mother passed on a and b alleles. a. Show the possible loci of these genes (specify alleles) on the image. Label both sister chromatids in each chromosome. (Note: Sister chromatids are products of replication.)b. Draw the four possible gametes formed after meiosis assuming there was no crossing over. Label the gene loci.A group of naturally occurring diploids of a species has 50 pairsof chromosomes.how many centromeres would you expect in Anaphase (mitosis)?by the end of the telophase (mitosis), what is the chromosome number of the species?in prophase (mitosis), how many chromatids should there be at this stage?For an organism with 3 pairs of chromosomes (6 total chromosomes, 2n = 6), draw chromosome diagrams for the following phases of meiosis: prophase I, metaphase I, anaphase I, telophase I, prophase II, metaphase II, anaphase II & telophase II. Be sure to draw the correct number of chromosomes and the correct number of chromatids per chromosome. Use a different color to represent each chromosome type (for example, use blue to indicate all copies of chromosome 1, red for all copies of chromosome 2, and green for all copies of chromosome 3).
- In the following diagram, designate each daughter cell as diploid (2n) or haploid (n).Discuss the following sets of terms: a. trisomy and triploidy b. aneuploidy and polyploidyVariations in Chromosome NumberAneuploidy Describe the process of nondisjunction and explain when it takes place during cell division.
- if a species of animal has 18 chromosomes in its diploid cells (2n=18). Describe what the metaphase chromosome arrangement would look like for this species in each of the following stages: mitosis, meiosis I, and meiosis IlSuppose 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)?An individual is heterozygous for a reciprocal translocation, with the following chromosomes: A • B C D E F A • B C V W X R ST • U D E F R ST • U V W X Q. Draw a picture of these chromosomes pairing in prophase I of meiosis.
