A female with the genotype xrxr

26/12/2020 Client: saad24vbs Deadline: 12 Hours

Virtual Lab: Sex-Linked Traits


Worksheet


Please make sure you have read through all of the information in the “Questions” and “Information” areas. If you come upon terms that are unfamiliar to you, please refer to your textbook for further explanation or search the word here: http://encarta.msn.com/encnet/features/dictionary/dictionaryhome.aspx


Next, complete the Punnett square activity by clicking on the laboratory notebook. Please be sure to note the possible genotypes of the various flies:


Female, red eyes


Female, red eyes


Female, white eyes


Male, red eyes


Male, white eyes


XRXR


XrXR


XrXr


XRY


XrY


When you have completed the Punnett square activity, return to the laboratory scene to begin the actual laboratory activity.


In this exercise, you will perform a Drosophila mating in order to observe sex-linked trait transmission. Please click on the shelf in the laboratory. Here you will find vials of fruit flies. On the TOP shelf, please click on one of the female vials (on the left side) and then drag it to the empty vial on the shelf below. Please repeat this step using one of the male vials (on the right side). These flies will be used as the parental (P) generation. You may switch your parent choices at any time by dragging out old selections and dragging in new flies. Use the Punnett square below to predict the genotypes/phenotypes of the offspring (Note: refer to the genotype table you created above if needed):


XR


XR


XR


Genotype: XRXR


Phenotype:Red eye, female


Genotype:XRXR


Phenotype: Red eye, female


Y


Genotype:XRY


Phenotype: Red eye, male


Genotype:XRY


Phenotype: Red eye, male


__50_% Female, red eye _0__% Female, white eye _50__% Male, red eye _0__% Male, white eye


When you are finished, click “Mate and Sort”.


You will now see information appear in the vials sitting on the next shelf below. These are the offspring of the parent flies you selected above, and they represent the first filial (F1) generation. In your “Data Table” on the bottom of the page and/or on Table I found at the end of this Worksheet, please input the numbers of each sex and phenotype combination for the F1 generation. These numbers will be placed into the first row marked “P generation Cross”.


You will next need to select one of the F1 female flies and one of the F1 male flies to create the second filial (F2) generation. Drag your selections down to the empty vial on the next shelf below and fill in the Punnett square below to predict the offspring:


XR


XR


XR


Genotype: XRXR


Phenotype:Red eye, female


Genotype:XRXR


Phenotype: Red eye, female


Y


Genotype:XRY


Phenotype: Red eye, male


Genotype:XRY


Phenotype: Red eye, male


__50_% Female, red eye _0__% Female, white eye _50__% Male, red eye _0__% Male, white eye


After clicking “Mate and Sort”, you will now have information on their offspring (the F2 generation) to input into your “Data Table” or Worksheet below. This information will be placed into the second row marked “F1 generation Cross”.


NOTE: there are additional lines remaining to use if your instructor requires the analysis of additional crosses.


Please finish this exercise by opening the “Journal” link at the bottom of the page and answering the questions.

Post-laboratory Questions:


Through fruit fly studies, geneticists have discovered a segment of DNA called the homeobox which appears to control:


Sex development in the flies


Life span in the flies


Final body plan development in the flies


The genotype of a red-eyed male fruit fly would be:


XRXR


XRXr


XrXr


A or B


None of the above


Sex-linked traits:


Can be carried on the Y chromosome


Affect males and females equally


Can be carried on chromosome 20


A and B


None of the above -2


A monohybrid cross analyzes:


One trait, such as eye color


Two traits, such as eye color and wing shape


The offspring of one parent


A female with the genotype “XRXr”:


Is homozygous for the eye color gene


Is heterozygous for the eye color gene


Is considered a carrier for the eye color gene


A and B


B and C


In T.H. Morgan’s experiments:


He concluded that the gene for fruit fly eye color is carried on the X chromosome


He found that his F1 generation results always mirrored those predicted by Mendelian Laws of Inheritance


He found that his F2 generation results always mirrored those predicted by Mendelian Laws of Inheritance


A and B


All of the above


In this laboratory exercise:


The Punnett square will allow you to predict the traits of the offspring created in your crosses


XR will represent the recessive allele for eye color, which is white


Xr will represent the dominant allele for eye color, which is red


All of the above


In a cross between a homozygous red-eyed female fruit fly and a white-eyed male, what percentage of the female offspring is expected to be carriers?


0%


25%


50%


75%


100%


In a cross between a white-eyed female and a red-eyed male:


All males will have red eyes


50% of males will have white eyes


All females will have red eyes


50% of females will have white eyes


In human diseases that are X-linked dominant, one dominant allele causes the disease. If an affected father has a child with an unaffected mother:


All males are unaffected


Some but not all males are affected


All females are unaffected


Some but not all females are affected


Journal Questions:


1. In a mating between a red-eyed male fruit fly and a red-eyed heterozygous female, what percentage of the female offspring is expected to be carriers? How did you determine the percentage?


2. In a mating between a red-eyed male fruit fly and a white-eyed female fruit fly, what percentage of the male offspring will have white eyes? Describe how you determined the percentage.


3. Hemophilia, a blood disorder in humans, results from a sex-linked recessive allele. Suppose that a daughter of a mother without the allele and a father with the allele marries a man with hemophilia. What is the probability that the daughter's children will develop the disease? Describe how you determined the probability.
