Homework Answers
- It can't be autosomal dominant because if it was, it would surely be shown by the progeny, as the progeny can get it from both mother and father. That is ,here both mother and father are affected so there is a greater chance for the progenies also to be affected , as they remain unaffected it surely mmeans the trait that caused the disease is autosomal but not dominant.
- It can't be Y linked because, if it was the male progeny will surely get affected as they contain Y chromosome for sure and they inherit it from their father only.
- It can't be X linked dominant condition because if it was then
both male and female progenies must show the disease. Let XA be
trait then father - XAY and mother - XAX then the progenies will be
Clearly shown it can't be X linked dominant.XA Y XA XAXA- affected XAY - affected X XAX - affected XY - unaffected - It can't be X linked recessive condition because if it was ( in
here father and mother are affected- mother wont act as carrier
rather affected)
Hence clearly shown it cant be X linked recessive as all male and one female of the progenie is affected.XC Y XC XCXC - affected XCY- carieer XC XCXC - affected XCY - affected
( As you haven't mentioned the question for which you need help, i will give answer to the first 4 questions)

Jill's father James has 8 siblings, 5 brothers and 3 sisters. All his siblings and himself suffer from symptoms related to eyes, some even have complete paralysis of eye muscles. James was told that they have a genetic disorder that runs in the family. James' fater is healthy; about mother he does not know- she died at her early 40th. What is the probable pattern of inheritance for this disorder? Select one: a. Autosomal dominant b. Autosomal recessive C. X-linked...

a.) Before individual II-2 had an affected
son, this family believed the condition followed a dominant mode of
inheritance. Why does the phenotype of III-1 support a
recessive rather than a dominant mode of inheritance?
b.) Could the mode of inheritance actually be dominant? Explain
using appropriate genetic terms.
c.) In order to better understand the risk of passing this
condition on to additional offspring, individual II-2 sought
genetic counseling which resulted in the drawing of this pedigree.

conditions
The pedigree from Part A is shown below. Fill in the most likely
genotypes of the indicated individuals in the pedigree. Note that a
dominant allele followed by an underscore (_) indicates that either
the dominant or the recessive allele may be present at the second
position. Drag one pink label (for condition A, autosomal
recessive) to each pink target. Drag one blue label (for condition
B, X-linked recessive) to each...

Biology 355, Spring 2020 Problem Set 5. Due 3/10/19 at 2PM on iLearn 1. Do we expect a son/daughter to have a trait if the trait is inherited in the following way (for each, please answer Y/N/P/W for yes, no, possibly, or 'what!? - that doesn't make sensell'). Please fill out the grid for each type of inheritance. For example, a X-linked dominant female-limited trait would look like this: Daughter Son Mom has trait Dad has trait Both have trait...

2. Analysis of a breeding history in pureb eding history in purebred dogs revealed a familial disease impacting some animals. Pedigree below shows the inheritance pattern in the breeding population. a) For each mode of inheritance listed below, indicate whether it is: 1: likely, 2: possible, or 3: impossible. You may make the following simplifying assumptions: 1) disease alleles are rare among animals in the general population; 2) only mothers contribute mitochondria; 1) Autosomal, sex influenced, dominant in males/recessive in...
