Genetics: Hardy-Weinburg, Alleles, Punnett Squares, and Genetic Drift

1) Consider the following population, represented by the genotypes of its members (N = 20). Is this population in Hardy-Weinberg Equilibrium? (see attachment for population). 2) If the parental generation of a particular population of humans has the following allele frequencies, E = 0.4/e = 0.6, what are the predicted genotyp

Set up and Complete Punnett Square

Bob and Sally recently married, Upon deciding to plan a family , both Sally and Bob find out that they are both heterozygous for cystic fibrosis, but neither of them has symptoms of the disorder. Set up and complete a punnett square for cystic fibrosis for this couple; when doing the Punnett Square, C=normal allele; and c=allele

List possible outcomes for mice offspring fur color

Two white mice mate. The male has both a white and a black fur color gene. The female has only white fur color genes. The fur color of the offspring depends on the pairs of fur color genes that they receive. Assume that neither the white nor the black gene dominates. List the possible outcomes. W=white and B=black

Biology please provide brief answers

1) Explain the importance of a control group in scientific experiments. 2) Briefly discuss the differences between prokaryotic and eukaryotic cells. 5) Discuss how researchers decide that populations of organisms belong to the same biological species? 7) The origin of life on Earth would not have been possibl

Mendel on patterns of inheritance

How did Mendel's approach to answering scientific questions differ from that of his contemporaries? How did Mendel's novel approach contribute to his success in describing how traits are inherited? What advantage did Mendel enjoy by choosing to study the garden pea? Describe three of the six major concluding principles Mendel hy

Genetics, genotypes, and testing paternity

This question tests your achievement of Cognitive skill CS2 (part (a)) and Practical and Professional skill PS1 (part (b)). John and George are brothers. They both claim to be the father of Child A and of Child B. The children are definitely siblings; they have the same mother. (i) From the data in Table 2, what is

Punnett Square

Complete all three parts and answer all questions. Remember to turn in Punnett Square for Part 2. Part 1: Genetics - 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 process

Mechanisms of generating antibody diversity

Diversity is very important in ensuring a sufficient immune response to accommodate the vast number of immune response. This solution describes in detail, with the aid of a diagram, how B cells generate diversity in the antibodies they produce.

Gene One Leadership Concepts

See attached files. Leadership Concepts Worksheet Assignment. Worksheet template attached along with example. The assignment has three purposes: (A) identify at least five key theoretical concepts from this week's readings, (B) relate each key concept to its application in an organizational setting, and (C) communicate w

Family pedigree

You receive 12 samples in your laboratory for genetic screening. The samples form two families. The first family is composed of samples: 1(Mom Smith); 2 (Smith Son 1); 3(Smith Daughter 1); 4(Smith Son 2); 5(Smith Son 3); 6(Smith Son 4); 7(Smith Son 5); 8(Smith Dad) and 9(Mom Jones); 10&11(Jones twin boys); 12(Jones Dad). Mom

Research Literature Analysis

Analyze two recently published research articles, one quanitative and qualitative study. These articles must be within the last 5 years (peer-reviewed.)

Twin study

Twin research is based on the notion that if identical twins (whose genes are exactly the same) reared apart are more similar than fraternal twins or non-twin siblings (who are similar, but not identical, in genetic inheritance) reared together, heredity must be the most important influence. According to this theory, if psychol

Sex-linked Genetic traits

Predict the parental genotypes for individuals expressing the dominant or the recessive trait. What sex generally expresses the recessive trait? Why?

Genetic variation and disease

1 Define the term "genetic variation." If a gene or locus has two alleles (A and a) in a population, what are all the possible genotypes? If the frequency of (A) allele = p, and the frequency of (a) allele is q, what is the frequency of all possible genotypes in this population? 2 What is the Hardy-Weinberg equilibri

GENETICS

In 1981, a stray cat with unusual curled-back ears was adopted by a family in Lakewood, California. Hundreds of descendants of this cat have since been born, and cat fanciers hope to develop the "curl" cat into a show breed. The curl allele is apparently dominant and carried on an autosome. Suppose you owned the first curl ca

Ethnic DNA testing

DNA testing There is a new service available to people that are African-American that can have a company test their DNA to see which region of Africa their maternal/paternal line originated from. A man who wants the test done walks into the clinic wearing clothes that happened to be pinpointing of having formed an individual re

From Genes to Proteins, Mutations & Inheritance of Traits or Genetic Disorders

Part 1: Genetics - 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 process of transcription, the information in the DNA codons of a gene is transcribed into RNA. Suppose that gene

Effect of migration on pehnotype frequency

Migration occurs at a constant rate between two populations of field mice. In one population, 65% of the population are white, in the other population, only 15% are white. What would you expect to happen to the allelic frequencies of these two population over time? Please provide am explanation of what will happen to the tw

Hardy-Weinberg Theorem

In a population of 100 rock pink plants, 84 individuals have red lowers while 16 have white flowers. Assume that white petals are inherited as a recessive trait (a) and red petals as a dominant trait (A). What are the frequencies p and q? In the next generation, what will be the equilibrium genotypic frequencies? Please sh

A) Step 1 - Transcription: During the process of transcription, the information in the DNA codons of a gene is transcribed into RNA. Suppose that gene X has the DNA base sequence 3'-TACCCTTTAGTAGCCACT-5'. Question: What would be the base sequence of RNA after transcription occurs? Turn this in. (In this particular exa
