7. The following diagram shows the two chromosomes in an individual heterozygous for an inversion,as well as genes A through F. The inversion is indicated by the thick line.What will happen if a recombination occurs in the region between genes A and B?a. A dicentric chromosome will be producedb. The telomeres of each chromosome will be lostc. The telomeres of each chromosome will be duplicatedd. An acentric chromosome will be producede. A normal recombination event

1) What type of chromosome abnormality does the father have? a)Duplication b)Inversion c)Deletion d)Translocation 2) Why does the father have a normal phenotype? a) Because the translocation was reciprocal. b) Because he has one wild-type copy of each chromosome. c) Because the translocation occurred only in the father's gametes. d) Because no genes are missing.

Choose the statement that is incorrect. a. A son can inherit a recessive allele on an X chromosome from either parent. b. An individual may inherit three or more of each type of chromosome characteristic or the species, a condition called polyploidy. c. A female child inherits one X chromosome from her mother and one from her father. d. Pedigree analysis can be used to determine a future childs chance of being born with achcondroplasia.
An abnormality in which there is one more or one fewer than the normal number of chromosomes is called (a) a karyotype (b) a fragile site (c) an aneuploidy (d) trisomy (e) a translocation
1.Describe the rearrangement in chromosomes A-C. indicate the specific markers genes flanking the crossover/breakage points (e.g., a translocation with breakpoints between markers X and Z). 2.Chromosome rearrangements can be caused by crossing over between repetitive DNA sequences. Draw a picture similar to Figure showing how crossovers between repetitive sequences could have produced chromosome rearrangement A. indicate the location and orientation of the repetitive DNA segments relative to the marker genes.
1. Using the diagram below, fill in the following Table to give the names of the genes that are present in the mnmE gene neighbourhood following single crossover homologous recombination. Part A ) Letter for gene in diagram Gene name A B C D E F Part B) Illustrate with an arrow on the above SXO diagram where a crossover would create a DXO mutation.
7) Picture a scenario where the maternal and paternal chromosomes randomly align all on the same side (all the maternal chromosomes on one side and all of the paternal chromosomes on the other side). If this happened in your body, this would theoretically result in the production of gametes that contained chromosomes which ALL originated from either your mother or your father. Are the chromosomes contained in these gametes identical to the ones you originally inherited from your mother and father? Why or Why not?
1. If a particular species of plant is made up of cells that each have 30 separate chromosomes, 15 of which appear to be paired in terms of size and shape, what is the “ploidy” of this plant? What is the term for these similar chromosomes? What is the ploidy of a different plant species in which the cells also have 30 separate chromosomes, but there seem to be 10 triplets of similar size and shape? How many different alleles can the same gene of a tetraploid plant have?
