In human beings, the gene for red green colorblindness (r) is sex linked and recessive to its allele for normal vision (R), while the gene for freckles (F) is autosomal and dominant over its allele for nonfreckled (f). A nonfreckled, normal visioned woman whose father was freckled and colorblind, marries a freckled, colorblind
There is a controversy about whether genetics or environment is more important in the development of our personalities. How does genetics impact behavior?
This is the genetic problem that I need to understand how to complete. Sand lizards in white sands new mexico: If for each species a lizard that was homozygous for the dark Mc1r allele had been crossed with a lizard that was homozygous for the light Mc1r allele the resulting F1 generation would have obtained the percentag
Can you help me with the following: Try this exercise: Hold out your right hand, place fingers together, and compare the length of your index (first) finger and ring (third) finger. The hormone "testosterone" is linked with masculine traits. The amount of testosterone exposed to in the womb affects finger length. The hi
The full problem is attached as a Word document, containing figures and pictures. The problem concerns a dominant and a recessive gene in lizards that affect the skin color of the lizard. The frequency of these genes in two different habitats is presented, and answers are given to several questions relating to the reasons
A woman referred to as individual A marries a man, individual B. Both have normal color vision. They have 3 children. Child AB1 is a son with normal color vision. Child AB2 is also a son but he is red green colorblind. The third child, son AB3, is red green colorblind as well. AB1 son marries a woman, S, with normal vision.
1)List the histological germ layers and describe organs originating from each layer. 2)Describe the differences between recessive, dominant, and co dominant genetic traits. Thanks Maria
Hemophilia is caused by a mutation in a gene on the x chromosomes. Draw a pedigree of a family where one daughter and one son of the couple's children has hemophilia. The other two children are not hemophiliac. Describe how one might figure out if these two have a chance ( and what that chance is ) of passing hemophilia on to th
The fathers blood group is AB. The potential sons blood group is B mother is blood group A. 1) Draw a mating/ cross diagram to show what the mothers geno type would be in respect to ABO blood group. 2) work out the probability that the child she conceived with the father would have a B blood group, please show f
As technology advances, the issue of "designer babies" and gene therapy seem to become a very real issue. In your opinion, do you think we should explore "modifying" genes? If so, in which cases? What do you think about the implications for altering genes for health reasons (e.g., a genetic disorder) vs. altering genes for co
I need help with analyzing the biological and humanistic approaches to personality. o Use Maslow's hierarchy of needs to discuss the extent to which growth needs influence personality formation. o Describe biological factors that influence the formation of personality. o Examine the relationship of biologica
This solution details the benefits and potential risks of genetic engineering, and the potential impacts on the environment and human health.
What are the benefits of genetic engineering versus the potential risks? Do you think genetic engineering provides useful information for the scientific investigation of our natural world or do you think that we should not "mess with Mother Nature"?
Please view the attached file for proper formatting. In rabbits, coat colour is controlled by multiple alleles of a gene. The coat colour of an ordinary wild type rabbit is called agouti, where each coat hair has bands of grey, yellow and black. The allele for agouti is represented by the capital letter C. Chinchilla rabb
Problem 1 A female mouse with yellow-mottled fur, eye-ear reduction and regular teeth was mated to a male mouse with dark gray fur, normal eye-ear size and irregular teeth. The F1 females were all wild type, that is, dark gray fur, normal eye-ear size and regular teeth. The F1 males had yellow-mottled fur, eye-ear reduction a
Please explain the biological ethics with the following: According to insurance providers they believe their companies are unfairly having to insure people with high probability of inheriting debilitative diseases. My question.. Can certain types of DNA screening protect individuals from these discriminatory actions?
We Select a clinical problem with a genetic component (i.e. Insulin Dependent Diabetes Mellitus Type I and HLA-DQ) in our area of interest. We can pick an existing paradigm or be creative and speculative. Just pick a gene or loci that has clinical impact for either diagnostic or prognostic reasons. infectious diseases and most

Explain the experiments in the following attached paper: "Telomere dysfunction promotes non-reciprocal translocations and epithelial cancers in mice"
The solution describes a research article testing the role of telomeres in cancer in mice. These questions are specifically addressed: (1) What is telomerase and what is it's role (2) Phenotypes of p53 knockout in mouse and humans- how do they differ? (3) Difference between carcinoma and sarcoma (4) Breakage-fusi
Working on my lab report in which we studied human variation. My partner and I were each heterzygous Rr and Rr One of us was the male and one the female Each of us flipped the coin with R on one side and r on the other. the following are the results. Our biobaby is a girl Round face RR Curly Hair RR no widows pea
Genetics problems, basic definitions, the Hershey Chase experiment, the genetic basis of sickle cell disease and DNA in cells.
Please Explain Each Problem (Excerpted from attachment) 1: The term phenotype refers to the _________ of an individual. 2: With respect to sickle cell anemia, I write that the genotype of an individual is AS. Which of the following statements are true? 3: If, in the Hershey Chase experiment, only 35S entered the bacter
The role of parents in the lives of the developing child would seem to be pretty obvious. But whether parenting matters has been an issue of some controversy. In the provocative book the Nurture Assumption, Judith harris (1998) argues that what parents do does not make a difference in their children's behavior. Spank them, hug t
What leadership elements within different positions support or hinder the change effort in the Gene One scenario? What factors of the business you researched do you think could be implemented in Gene One to make its change effort more successful? After analyzing Gene One's options for its future, answer the following ques
You are attending a conference on sustainable development in low-income countries at Colorado Technical University. During your lunch break, you walk to the cafeteria and notice that one vendor is advertising "GMO-free" food. You purchase and enjoy a sandwich from this vendor. Later that day, you decide to do some research on ge
Suppose you are working in a research lab investigating the expression of the enzyme hexokinase in Drosophila. Specifically, you are interested in expression patterns of this enzyme in Drosophila in the larval stage vs. the adult fly stage. After collecting data from both larvae and adult flies, your analyses indicate that the
