    Mendelian Genetics Problem

    A cross between plants with red flowers and plants with white flowers produces plants with pink flowers. If two of these pink-flowered plants are crossed, what is the chance that pink-flowered plants will be produced? 0%, 25%, 50%, 75% or 100%

    Drosophila melanogaster

    Just want to understand the genetics of what happens and why with punnet squares. The theory behind why it happens.

    In heritance of hemophilia

    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

    Determining blood type inheritance

    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

    View of technology advances on designer babies

    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

    Completed Punnett Square and Answers to all questions

    Part 1: Genetics â?" From Genes to Proteins, Mutations (Chapter 10) Overview: Genetic information in DNA is transcribed to RNA and then translated into the amino acid sequence of a Protein. A) Step 1 - Transcription: During the process of transcription, the information in the DNA codons of a gene is transcribed into RNA.

    Biological and Humanistic Approaches to Personality

    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

    hemophilia probability

    A couple is both phenotypically normal, but their son suffers from hemophilia. Draw a pedigree that shows the genotype of the 3 individuals. What fractions of their children are likely to suffer from hemophilia? What fractions are likely to be carriers?

    Calculating Phenotypes/Genotypes in Rabbits

    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

    Genetics (DNA, Mutations, Cell Division, Protein Synthesis)

    Biotechnology allows us to use living organisms or their processes for human needs or purposes. Currently, this topic includes such general examples as cloning, stem cells (adult, umbilical cord, and embryonic), DNA fingerprinting, biological warfare, bioremediation, genetically modified organisms, vaccines, and transgenic plant

    Genetics, Genes, Proteins, Mutation, Punnett Square

    Complete all three parts and answer all questions. Remember to turn in Punnett Square for Part 2. Part 1: Genetics â?" From Genes to Proteins, Mutations Overview: Genetic information in DNA is transcribed to RNA and then translated into the amino acid sequence of a Protein. A) Step 1 - Transcription: During the proces

    Biological Influences

    1. Describe neurotransmitters in terms of what they are, their general function within the body, and their impact on behavior. 2. Discuss the connection between neurons and neurotransmitters. 3. Pick two neurotransmitters and discuss their general functions in our bodies. Also discuss each neurotransmitterâ??

    Genetic problems regarding gene mapping of linked genes

    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

    Ethics and Biology in DNA screening

    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?

    Clinical background to sickle cell anemia

    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

    Show, with examples, how the 'pyrosequencing' method has been useful for very high throughput applications.

    Genetic Testing in the work place

    Need help in writing a paper regarding the topic covered below.

    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
