Summary Introduction
Introduction:
A display of all the chromosome of an organism is called karyotype. A karyotype consists of number and appearance of the chromosome in a nucleus. It is used to detect the deviation that occurs in the chromosome. It is also used to check the abnormalities of the chromosome.

- A patient has mental deficiency, a short stature, and the mongolian type of the eyelid fold. The microscopical examination of the patient's karyotype revealed the presence of trisomy on the 21-st chromosome. What do we call the disease which is caused by this chromosomal abnormality? Select one: a. Down's syndrome. b. Klinefelter's syndrome. O c. Turner's syndrome. d. Edward's syndrome. e. Patau syndrome.arrow_forwardPart of the karyotype of a diploid individual who is heterozygous for one chromosomal rearrangement is shown in the diagram. The chromosomes involved in the rearrangement, and their homologous pair, are shown. The location of each gene is labeled using horizontal lines and the name of each gene is labeled using letters or numbers. Answer the following questions about the diagram. A. What rearrangement is shown? Be as specific as possible. B. Describe a mutation scenario that could cause this rearrangement to be formed.

Which cells are considered haploid, gametes or somatic cells?arrow_forwardIn a karyotype of a man whose wife has had several miscarriages, it was discovered that he had onlv 45 chromosomes. However, he displayed no obvious phenotypic defects. Furthermore, one of the chromosomes of pair 15 was abnormally long. Which of the following terms best describes the condition of this man? a. monosomy b,. trisomy c. tetrasomy d. translocation carrier e. edward syndormearrow_forward1. The figure below represents a karyotype performed on a somatic cell of an unknown organism. Answer the following questions using the figure. a. Circle (and label) 3 different sets of homologous chromosomes? b. This individual is heterozygote for gene A (Aa), Homozygote recessive for gene B (bb) and gene homozygote dominant for gene c (CC). Also, gene B and gene C are linked. Using the homologous chromosomes you circled in part a), provide a representation of the location of the A, B and C, genes and alleles on the homologous chromosomes and sister chromatids in such a way that is consistent with the scenario described above in part b). Choose the chromosomes of your liking to show an appropriate representation. TMIID IL MIarrow_forward
- Discuss the principles of the chromosome theory of inheritance. Which principles were deducedvia light microscopy, and which were deduced from crosses? What modern techniques couldbe used to support the chromosome theory of inheritance?arrow_forwardGive typing answer with explanation and conclusion to all parts The chromosomes drawn below are found in a human skin cell. The lines represent the chromosomes themselves. The letters indicate the location of a particular version of a gene. a) T/F An individual’s offspring are more likely to inherit a D1 and R together than a D1 and T9 together. b) T/F About 50% of the egg cells from this individual will have both T9 and BA5. c) T/F Because r is recessive, the frequency at which the r version of the gene occurs in a population is lower than the frequency at which the R version occurs in the population. d) T/F If the protein produced by the BA gene is involved in the formation of ovaries, then the BA gene is likely located on a sex chromosome. e) T/F Because the genes shown here are found in skin cells, these genes code for proteins required for skin cell function.arrow_forwardIn a college genetics laboratory course, a healthy student constructs a karyotype from a cell from inside her cheek. She finds only one chromosome 3 and one chromosome 21, plus two unusual chromosomes that do not seem to have matching partners. a. What type of chromosomal abnormality does she have? b. Why doesn’t she have any symptoms? c. Would you expect any of her relatives to have particular medical problems?arrow_forward
