Communication

Communication is a method of transferring information between two persons or organisms. Communication is possible using mutually understood behaviors such as signs, symbols, or language. In the year 1980, S. F. Scudder proposed communication theory. According to his ideas, all living beings on the earth communicate, but the methods of communication differ. Communication skills are now part of soft skills.

Question

Red-green color blindness in humans is due to an X- linked recessive gene.

Expert Solution

Step 1

Red-green color blindness is the most common variety of color deficiency in humans. It happens to people who can’t see shades of red and green the same way as people with normal color perception do
X-linked recessive inheritance refers to genetic conditions associated with mutations in genes on the X chromosome. A male carrying such a mutation will be affected, because he carries only one X chromosome.
A female carrying a mutation in one gene, with a normal gene on the other X chromosome, is generally unaffected
Males are affected more often than females, because the gene is located on the X chromosome.

Redgreen color blindness is an X-linked recessive disorder in humans. Your friend is the daughter of a color-blind father. Her mother had normal color vision, but her maternal grandfather was color-blind. What is the probability that your friend is color-blind? (a) 1 (b) (c) (d) (e) 0
Red–green color blindness in humans is due to an X-linked recessive gene. Both John and Cathy have normal color vision. After 10 years of marriage to John, Cathy gave birth to a color-blind daughter. John filed for divorce, claiming that he is not the father of the child. Is John justified in his claim of nonpaternity? Explain why. If Cathy had given birth to a color-blind son, would John be justified in claiming nonpaternity?
A man with X-linked color blindness marries a woman with no history of color blindness in her family. The daughter of this couple marries a normal man, and their daughter also marries a normal man. What is the chance that this last couple will have a child with color blindness? If this couple has already had a child with color blindness, what is the chance that their next child will be color blind?
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%
Red–green color blindness is an X-linked recessive trait. Susan has normal color vision, but her father is color blind. Susan marries Bob, who has normal color vision. Q. Susan and Bob have a daughter named Betty, who has normal color vision. If Betty marries a man with normal color vision, and they have a son, what is the probability that the son will be color blind?
Achondroplasia,is characterized by difficulty converting cartilage to bone and thus results in shortened limbs. This trait is autosomal dominant. (A = achondroplasia allele; a = average height allele.) A husband and wife both have achondroplasia. The couple have a total 12 living children: 6 boys and 6 girls. The husband is colorblind, which is an X-linked recessive trait, and the wife believes there is a chance she is a carrier of colorblindness, since that trait runs in her family. One of the couple’s daughters and three of their sons are colorblind. (Xc = colorblindness allele; XC = normal color vision allele.) a) Please list all of the different gametes that the husband can produce. b) Please list all of the different gametes that the wife can produce.

One of the couple’s daughters and three of their sons are colorblind. (Xc = colorblindness allele; XC = normal color vision allele.) A. Is the mother a carrier of the colorblindness allele? Please explain the meaning of the term "carrier", and answer this question, based upon all of the information provided.
Two parents who do not have color blindness have a daughter who has only one X chromosome and is color-blind (this genotype is written XO since she is missing an X). Color blindness is inherited in an X-linked recessive manner.
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
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…
