- Answer the following: a. Assume that you are married and by chance upon submission for an amniocentesis prenatal checkup it resulted that your baby has more than the total number of chromosomes. What will your final decision to this finding? b.“All organisms have a constant chromosome number. The chromosomes’ sizes vary. If by chance the two sentences are not found in the organisms, what will happen ?What is the chromosome number of the individual? Based from the karyotype, identify the name of the genetic condition of the individual. List down two (2) distinctive characteristics of the affected individual.How to draw a branch diagram to provide the answers Figure1 is questions.Figure 2 is my answers. Since I don't know how to do this question, how to draw a branch diagram of two alleles on a chromosome. If my answer is not correct, please correct it and give me the correct answer. THX.
- Answer the following: 1. What are the different types of chromosomes? Draw and discuss each. 2. Discuss the following types of sex determination and give example. a. Male Heterogamety b. Female Heterogamety c. HaploDiploidy System d. Ratio System e. Environmental Method through Position, Temperature Dependent, Location Dependent 3. What is dosage compensation? Give its importance. asapMatch the term with the correct definition or example Question 27 options: Product of a cross between true breeding plants that make yellow peas and true breeding plants that make green peas. A description of the alleles present in an individual at one or more loci. Example: MM or Mm or mm. Example: 11q1. 4-q2. 1", meaning it is on the long arm of chromosome 11, somewhere in the range from sub-band 4 of region 1 to sub-band 1 of region 2. Under a microscope, these look exactly the same. The centromere, banding, long arm, short arm, overall length, gene locations, and order of genes are exactly the same. However, nucleotide sequences in genes on the two chromosomes can differ. the unit of heredity, the sequence of nucleotides in the exon regions specifies the sequence of amino acids in a particular polypeptide Brown allele in eye color Red eye in fruit flies Ability to synthesize alcohol dehydrogenase…Hi, could your please answer this question? I'm so confused. The following diagram (picture added) shows 2 pairs of autosomal chromosomes in a karyotype of a biological woman. Based on the karyotype, a genetic counselor determined that there is evidence that a translocation occurred between two non-homologous chromosomes. The other 21 pairs of chromosomes are NOT shown in this diagram. Assume no chromosomal aberrations occurred in the other chromosomes. As a student-researcher, what would be your answer if the genetic counselor asks you if you can determine whether the translocation occurred in a somatic cell, germ-line cell, or whether this can even be determined from the figure? provide the reasoning for your answer.
- Diploid Number of chromosomes, Sex Chromosomes, (+/- whole) Chromosome (+/- partial) e.g. 47, XY, +14 = male with trisomy of chromosome 14 e.g. 46, XX, 1q+ = female with a partial increase to the length of the long arm of chromosome 1 (partial increases or decreases to a single chromosome still have the same diploid number) What is the notation for the following cases? ( A woman having Turner syndrome.Use the following information as the basis for answering all questions: A diploid eukaryotic organism has 4 unique chromosomes.

How many total telomeres are in a germ cell in the testis of this organism that is in Anaphase of Meiosis II?Consider the example of the fusion of chromosome 21 and 14. By itself, this fusion does not cause any phenotypic differences in the carrier individuals. However, the children of carriers have a very high rate of down syndrome, as well as low fertility. Explain why this is? Be specific about what differences in chromosome number may occur in offspring, and how this occurs. Please answer asap and in short and content should not be palgarised please answer asap Consider the example of the fusion of chromosome 21 and 14.

- Diploid Number of chromosomes, Sex Chromosomes, (+/- whole) Chromosome (+/- partial) e.g. 47, XY, +14 = male with trisomy of chromosome 14 e.g. 46, XX, 1q+ = female with a partial increase to the length of the long arm of chromosome 1 (partial increases or decreases to a single chromosome still have the same diploid number) What is the notation for the following cases? ( A male having Patau syndrome (trisomy 13)People with Down syndrome have an extra copy of chromosome 21, for a total of 47 chromosomes. However, in a few cases of Down syndrome, 46 chromosomes are present. This total includes two normal-looking chromosomes 21, one normal chromosome 14, and a longer-than-normal chromosome 14. Interpret this observation. How can these individuals have 46 chromosomes?Human sex chromosomes are XX for females and XY for males. a. With respect to an X-linked gene, how many different types of gametes can a male produce? b. If a female is homozygous for an X-linked allele, how many different types of gametes can she produce with respect to this allele? c. If a female is heterozygous for an X-linked allele, how many different types of gametes can she produce with respect to this allele?
