Why are individuals with an extra chromosome 21, that causes Down syndrome, more numerous than individuals with an extrachromosome 3 or chromosome 16?
A.] There are probably more genes on chromosome 21 than on the others
B.] Chromosome 21 is a sex chromosome and chromosomes 3 and 16 are not
C.] Down syndrome is not more common, just more serious
D.] Extra copies of the other chromosomes are probably fatal

- 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.arrow_forwardBPA and Abnormal Meiosis In 1998, researchers at Case Western University were studying meiosis in mouse oocytes (germ cells) when they saw an unexpected and dramatic increase of abnormal events (FIGURE 12.6). Improper segregation of chromosomes during meiosis is one of the main causes or human genetic disorders. The spike in abnormal meiosis began right after the mouse facility started washing the animals' plastic cages and water bottles in a new, alkaline detergent. The detergent had damaged the plastic, which as a result was leaching bisphenol A (BPA). BPA is a synthetic chemical that mimics estrogen, the main female sex hormone in animals. Though it has since been banned for use in baby bottles, BPA is still widely used to manufacture other plastic items and epoxies (such as the coating on the inside of metal cans of food). BPA-free plastics are often manufactured with a related compound, bisphenol S (BPS), that has effects similar to BPA. FIGURE 12.6 Abnormalities in meiosis that occurred after exposure to BPA. Top, the most abnormal meiosis events occurred in mice that were housed in damaged plastic caging with damaged plastic bottles. Damaged plastic releases BPA. Bottom, fluorescent micrographs show the chromosomes (red) and spindle (green) in nuclei of mouse germ cells in metaphase I. A Normal metaphase; BD abnormal metaphase. What percentage of mouse oocytes displayed abnormalities of meiosis with no exposure to damaged caging?arrow_forwardThe X-linked gene responsible for DMD encodes a protein called dystrophin that is required for muscle function. Dystrophin protein is not secreted—it remains inthe cells that produce it. Given what you know aboutBarr body formation, do you think that females heterozygous for the recessive DMD disease allele could havethe disease in some parts of their bodies and not others?arrow_forward
- Duchenne muscular dystrophy (DMD) is caused bya recessive mutant allele of an X-linked gene calleddystrophin. Rarely, females have disease symptomsas severe as those in males hemizygous for therecessive allele. These females are heterozygous forX-autosome reciprocal translocations where the Xchromosome breakage occurred in the middle of thedystrophin gene, breaking it into two pieces.a. If it is equally likely for X chromosome inactivation to spread from either of the X chromosomeinactivation centers (XICs; see Fig. 12.15) in thecells of this patient, what proportion of her cellswould you expect to have normal function of thedystrophin gene?arrow_forwardAlbinism is an autosomal recessive condition where little or no melanin pigment is produced. Awoman (call her W) had an affected brother (B). This woman's daughter (M) is planning to have achild. The intended father (F) in this mating had a sister (S) who has albinism. W's father is red-green color blind (an X-linked recessive disorder). F's father is also red-green color blind. All other family members have normal vision. Re-draw the pedigree of thisfamily to include this extra information. Use defined symbols to indicate genotypes. g. Determine the probability that F will pass on red-green color blindness to his future children.h. Determine the probability that M is a carrier for red-green color blindness or for albinism i.Determine the probability that M is a carrier for red-green color blindness and for albinism i.Determine the overall probability that this couple's first child will be affected by bothconditions. k. Using the same genotypes as in part j for the couple, determine…arrow_forwardThis pedigree consist of cystic fibrosis that is an inherited disease caused by f a recessive allele.

If someone could please help with work shown and an explanation it would help so much! Thank you!! 1a. The pedigree below represents inheritance of rare condition (filled symbols used for affected individuals). Test the hypothesis of X-linked dominant inheritance by assigning alleles (A or a) to sex chromosomes of all individuals in generations I and II. Does the X-linked dominant hypothesis agree with the data? It not, indicate all at least 2 individuals by generation and number (e.g. II-8) that are not consistent with the genotype you’ve proposed for the individuals in generation I. 1b. Test the hypothesis of autosomal dominant inheritance by assigning alleles (A or a) to autosomes of all individuals in the pedigree (generations I – IV). Does the autosomal dominant hypothesis agree with the data? It not, indicate all individuals by generation and number (e.g. II-8) that are not consistent with the genotype…arrow_forward
