Now assume that the pedigree shown in question 1 shows the inheritance of a rare genetic disease.
a) The disease is most likely autosomal dominant
b) The disease is most likely autosomal recessive
c) The disease is equally likely to be either autosomal dominant or autosomal recessive, but cannot be x-linked
d) Cannot be determined from the information given
According to the pedigree below, what mode of inheritance is occurring?
A)Autosomal dominant
B)Autosomal recessive
C)X-linked
Consider the two very limited unrelated pedigrees shown here. Of the four combinations
of X-linked recessive, Xlinked dominant, autosomal recessive, and autosomal dominant,
which modes of inheritance can be ruled out in each case?

(b) What are the chances that their daughters will be carriers of the disease? (c) What percentage of their children are likely to have the disease?arrow_forwardAlbinism in humans is inherited as a simple recessive trait. For the following families, determine the genotypes of the parents and offspring. (When two alternative genotypes are possible, list both.) (a) Two normal parents have five children, four normal and one albino. (b) A normal male and an albino female have six children, all normal. (c) A normal male and an albino female have six children, three normal and three albino. (d) Construct a pedigree of the families in (b) and (c). Assume that one of the normal children in (b) and one of the albino children in (c) become the parents of eight children.

- Suppose that a grandfather, mother, and son all have the same homozygous dominant genotype for a gene that controls facial hair growth. The grandfather and son have thick beards, but the mother has no significant facial hair. What type of hon-Mendelian inheritance is this? Oa) Sex-influenced inheritance O b) Sex-limited inheritance Oc) Onset of genetic expression D d) X-linked dominant inheritancearrow_forwardSuppose that a grandfather, mother, and son all have the same homozygous dominant genotype for a gene that controls facial hair growth. The grandfather and son have thick beards, but the mother has no significant facial hair. What type of non-Mendelian inheritance is this? O a) Sex-influenced inheritance Ob) Sex-limited inheritance Oc) Onset of genetic expression O d) X-linked dominant inheritancearrow_forwardRegarding 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.arrow_forward
- 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.arrow_forwardWhat feature(s) of this pedigree indicate(s) dominant inheritance?arrow_forwardA boy with Klinefelter syndrome (47,XXY) is born to a mother who is phenotypically normal and a father who has the X-linked skin condition called anhidrotic ectodermal dysplasia. The mother’s skin is completely normal with no signs of the skin abnormality. In contrast, her son has patches of normal skin and patches of abnormal skin. (a) Which parent contributed the abnormal gamete? (b) Using the appropriate genetic terminology, describe the meiotic mistake that occurred. Be sure to indicate in which division the mistake occurred. (c) Using the appropriate genetic terminology, explain the son’s skin phenotype.arrow_forward
