The shape of a heliodor is an X-linked trait. Male heliodors inherit two X chromosomes, while the females inherit an X and a Y chromosome. The recessive allele codes for the common bell-shape while the dominant phenotype is a round shape . Hudson is a round male and has offspring with Heidi, a bell-shaped female. They already have one daughter, Hannah, who is shaped like her mother. If their next child is a boy, there is a _____% chance it will be round.

The allele for color-blindness is carried on the X chromosome. Making color blindness (a recessive trait) an X - linked trait. A colorblind make and a carrier female for color blindness. (But is not colorblind herself) have a child. Show your work! A) what is the % chance that their son will be color blind? B) what is the % chance that their daughter will be color blind?
The shape of a heliodor is an X-linked trait. Male heliodors inherit two X chromosomes, while the females inherit an X and a Y chromosome. The recessive allele codes for the common bell-shape while the dominant phenotype is a round shape . Hudson is a round male and has offspring with Heidi, a bell-shaped female. They already have one daughter, Hannah, who is shaped like her mother. The reason for your answer above is: a.Females heliodors inherit two X chromosomes, so it is less likely they would only inherit two recessive alleles for being bell-shaped. b.Males heliodors inherit two X chromosomes, so it is less likely they would only inherit two recessive alleles for being bell-shaped. c.Males only need to inherit one recessive allele to be bell-shaped. d.Being male or female has no impact on the shape of a heliodor
Amanda Sefton (Daytripper) has normal fingers and toes and normal color vision. Her mother is normal in all respects, but her father is color blind (X- linked recessive) and syndactylous (autosomal dominant). Kurt Wagner (Nightcrawler) is color blind and syndictylous. His mother has normal color vision and normal fingers and toes, but he didn't know his father. As their genetic counselor, answer the following questions based on Kurt and Amanda marrying and starting a family. What is the probability of having a child that has syndactyly? (Enter your answer as a decimal; Example = 0.8782)
Red-green color blindness is inherited as a sex-linked recessive trait. The gene is found on the X chromosome. How can a man with normal color vision father a daughter who is red-green color-blind? Group of answer choices The man is heterozygous for red-green color blindness. The woman with whom he mates is red-green color-blind. He can't (unless there is a mutation). The man's mother carries an allele for red-green color blindness, and the expression of the trait skipped a generation.
Geneticists are concerned about three different genetic conditions present within their family. Achondroplasia is an autosomal dominant genetic disorder that results in short-limbed dwarfism. (A = achondroplasia allele; a = average height allele). Red-Green Color blindness is an X-linked recessive genetic disorder (Xc = color blindness allele; XC = normal color vision allele). The 7-year-old son has an autosomal recessive form of deafness. (h = deafness allele; H = normal hearing allele.) All three family members were karyotyped, and additional genetic testing was performed to determine the chromosomal location of the genes being studied. The figures below show the karyotypes of the mother and father with respect to the chromosomes containing the three genes mentioned above. Question: The couple’s 7-year-old son has all three of these genetic conditions (achondroplasia, color blindness and deafness). Taking into consideration the genotypes of his parents, what is the complete…
Red-green colorblindness is a X-linked recessive disorder. Jill has normal vision but her dad was color blind. Tom has normal color vision. Jill and Tom have a daughter with Turner syndrome (XO) and she is color blind? Write out the genotype of the daughter. How did the daughter inherit her color blindness? Which parent did she inherit her single X chromosome from? Which parent had a non-disjunction event during gametogenesis? How do you know?
Color-blindness is an X-linked recessive disorder. Under what circumstances will this condition manifest in a child? Top of Form If the child is a male and its mother has the recessive allele If the child is a female and its father has the recessive allele If the child is a female and its mother has the recessive allele If the child is a male and its father has the recessive allele
The discovery of sex-linked traits came from a genetic experiment on flies. A white eyed male fly was discovered. The trait was discovered to be sex-linked recessive. To guarantee that the white eye trait is recessive, he did a cross of XRXr and XrY. Complete the Punnett Square. State the genotypes and phenotypes of the offspring.
X-linked ichthyosis is an X-linked recessive trait that manifests in part as dry, scaly skin (“ichthy-” = fish or fish like). Suppose a couple are considering having a child together. Parent A is heterozygous for the ichthyosis allele while Parent B is hemizygous negative for the ichthyosis allele. What is the probability their child would be unafflicted with ichthyosis but be a carrier of the ichthyosis-causing allele? a.0% b.25% c.50% d.75% e.100%
Color blindness is an X-linked recessive disease. A female and a male with normal vision have 4 children. The phenotypes of the children are listed below: 2 Colorblind males, 1 normal vision female, one normal vision male. Given these results, the female must be a carrier for colorblindness. True False
