In humans, the genetic disease cystic fibrosis is caused by a recessive allele (a). The normal (healthy) allele is dominant (A). What is the genotype of someone who has cystic fibrosis? What are the two different genotypes that a healthy person could have? If two people were both heterozygous for the cystic fibrosis gene, what fraction of their children would be likely to have this disease? Hint: Draw a Punnett square to figure it out.
Alleles of a single gene control whether individuals have a "hitchhiker's thumb" or "straight thumb." You are studying the inheritance of hitchhiker's thumb (straight thumb is dominant) in your family. Assuming that this trait is inherited on an autosome (ie, not a sex-chromosome), please answer which of the following outcomes ARE POSSIBLE under normal circumstances. (Choose all that apply.) 1) Two parents have straight thumb, but they have a child with hitchhiker's thumb. 2) Two parents have hitchhiker's thumb, but they have a child with straight thumb. 3) Mother has straight thumb, father has hitchhiker's thumb, child is homozygous dominant for the allele. 4) Mother has straight thumb, father has hitchhiker's thumb. They have one child with straight thumb, another child with hitchhiker's thumb.
Red-green color blindness is inherited as an X-linked recessive (Xc). If a color-blind man marries a woman who is heterozygous for normal vision, what would be the expected phenotypes of their children with reference to this character? In your answer, specify in your phenotype descriptions the gender of the children. (For example, don’t just say 75% of the children would be colorblind – you would instead say 100 % of the daughters would be colorblind and 50% of the sons would be colorblind. Note that this is not a correct answer; it is just to give you an idea of how to explain the correct phenotypes of the cross.)___
Q6. Guinea pigs, which were homozygous for long, black hair were crossed with ones which were homozygous for short, white hair. All the F1 offspring had short, black hair. (a) Using suitable symbols, draw a genetic diagram showing parents genotypes, to explain this result in F1 offspring. (b) Complete the Punnett square to show the results of interbreeding the F1 offspring. Gametes
What is the pattern of inheritance? Please Provide a specific reason that justifies your selection of this pattern of inheritance as the correct one, and also explain why each of the other two alternatives are not correct. As part of your answer, you must include the phenotypic ratio, including the sex of the offspring, that you would expect to find in each of the three possible scenarios. Please specify whether this pattren of inheritance is (i) rare X-linked recessive, (ii) sex-influenced, or (iii) sex-limited.
Regarding Mendelian inheritance in diploid individuals, (Read each statement carefully. Select all of the statements below that are true (that you agree with). Leave any statements that are false (that you do not agree with) un- selected.) a diploid individual receives two copies of every autosome from the previous generation. for every autosomal gene inherited by an individual, both copies can come from one parent. a diploid individual gives two copies of every autosome to a child in the next generation. to be diploid means that two independent genes are specified in the individual's genotype.
raccoons may have wide, medium-sized, or narrow bands around their tails. They may also havethe habit of washing all, or some of their food, or do not wash their food at all. a) assign genotypes to the phenotypes mentioned (see attached table) b. What mode of inheritance would most likely be exhibited by these traits if crosses were made? c. If two raccoons with medium-sized tail bands and have the habit of washing some of theirfoods will be crossed, what is the probability of having F1 raccoons with: c.1 wide tail bands that won’t wash any of their food? c.2 the same genotype as the parent raccoons? d. If a raccoon with a wide tail band that washes only some of its food is crossed with a raccoonwith a narrow tail band that doesn’t wash any food, what percentage of their offspring wouldbe medium-tailed and washes all its food? Show COMPLETE cross.
Marfan syndrome is a disease caused by a rare dominant allele of the fibrillin-1 gene. Fibrillin-1 is an important component of the extracellular matrix, and people with the disease-causing allele have abnormal connective tissue. An affected mother (Marta) and an unaffected father (Joe) have one unaffected daughter (Luisa - she does not exhibit any traits of the syndrome). If Luisa has a child with Nico (unaffected), what is the probability that her child will inherit Marfan syndrome? Select one: a. 50% b. 25% c. 100% d. 0% e. 75%
Assume that a gene controls the expression of a trait in which affected children occur only in families where one or both parents are also affected; children who are normal may have parents who are (1) both normal, (2) one normal and one affected, or (3) both affected. Is the gene for the affected condition completely dominant, co-dominant, incompletely dominant or recessive?
The pedigree below tracks the inheritance of a genetic disorder through a family's generation. Determine the probable inheritance mode for the trait shown in the affected individual (the shaded symbols) by answering the following questions. I II 2 3 4 5 7 III 2 3 6 7 8 5 (i) Based on the pedigree, Y-linked inheritance can be excluded at a glance. Give your reason. (ii) What TWO (2) other modes of inheritance can be definitely excluded? Explain your answer. Of the remaining modes of inheritance, which is the most likely? Which is less likely? Explain your answers. (ii)
