SEX-LINKED TRAITS 8. Create a Punnett square to determine the offspring that would result from a cross between a woman with normal vision, who carries the allele for color-blindness, and a man who has normal vision. Note: color-blindness is an X-linked recessive tret What are the genotypes of the parent? List all possible genotypes of the offspring. male, normal male, color-blind female, normal vision female, carrier 50% Co hat percentage of their sons would be color-blind?

D. 25% orme condition. The male is XX and the female is XY. But X-linked genes have the same effects in mugwumps as in humans. A recessive X-linked allele "n" produces red-green color blindness. The dominant allele "N" produces normal color vision. If a female mugwump with normal color vision mates with a male mugwump, phenotypically normal for color vision but whose mother was color blind, what is the probability that a son from that mating will be color blind?...

A color-blind female has children with a male that has normal vision. Which of the following is the most likely outcome for their potential offspring? A All female children will be color blind. B All of their children will have normal vision. C All male children will be color blind. D They will only have female children.

4. Now, assume that a F1 male and a F1 female offspring produced by the cross in #3 above mate with each other. F1 offspring : XXGgBb and XYGgBb Note: You can ignore the X and Y chromosomes here in question 4. Why? The traits of interest (fire-breathing and laser-shooting) are autosomal, so the sex of the fly (XX=female or XY=male) will not impact the trait expressed. You only need to follow the inheritance of chromosomes 2 and 3 for...

7. What genotypes are expected in the offspring from mating a black Lab heterozygous for both coat color and normal eyes with a chocolate Lab that is blind from PRA? (Use the FOIL method to determine the gametes) The cross is BbNnx bbnn. After determining the gametes formed by each parent, complete a Punnett square showing the offspring 8. In cattle, red (R) is incompletely dominant over white (r), resulting in three phenotypes: red, roan, and white....

Hemophilia Procedure: Create a Punnett square that determines the probability of male offspring having hemophilia when the father has hemophilia (Y Xh) and the mother is a carrier (XH Xh). Record the results. What were the possible genotypes of the offspring? Out of only the male offspring, what is the probability (percentage) of a male being afflicted with hemophilia of only the male offspring? How many females (what number of females) would be expected to have hemophilia out of the...

Punnett Square for Question #4 is a the top
Punnett Square Genotypic ratio: Phenotypic ratio: 5. Purple flowers (P) are completely dominant over white flowers (p). If a pea plant is heterozygous for purple flowers, can any of this plant's offspring have all purple flowers? Think about the different genotypes with which you can cross the hetero- zygous parent: homozygous dominant, heterozygous, and homozygous recessive. Use three Punnett squares to show your work for each possible phenotype. Heterozygous purple pea...

Imagine that a couple is planning to have children. The Male is heterozygous for tongue rolling and homozygous dominant for unattached earlobes. The female is homozygous recessive for tongue rolling and heterozygous for unattached earlobes. The ability to roll ones tongue is dominant [R] over the non rolling tongue [r]. Unattached earlobes [U] are dominant over attached earlobes [u]. complete a Punnett square for this cross and record the probabilities for genotypes and phenotypes of the offspring as ratios.
