Hi, I don't have a problem with the question itself but i don't understand how my textbook use probabilty in solving the problem. How many genetically different eggs could be formed by a women with the following genotypes? Aa bb CC DD Now it's obvious that one gamete will have (A b C D) and the other gamete will hav
1. Draw all possible chromosome configurations in Metaphase I with a dihybrid AaBb. 2. Do the same things as in question 1 for the genotype AaBbCc. 3. How many types of gametes would result from a dihybrid AaBb? What are they? 4. What portion of the zygotes will be a. AaBBCc? b. AABBCc? c. AaBbCc?
For the problems attached please show the symbols used in human pedigree analysis and/or Punnett Square if needed. Please also explain answers. Thank you! --- 1. A sex-linked recessive allele c produces a red-green colorblindness in humans. A normal woman whose father was colorblind carries a colorblind man. a. What
1. a. The ability to taste the chemical phenylthiocarbamide is an autosomal dominant phenotype, and the inability to taste it is recessive. If a taster woman with a nontaster father marries a taster man who in a previous marriage had a nontaster daughter, what is the probability that their first child will be (1) A nontaster
There are a 100 feral pigs on a island in which 75 individuals are solid black and 25 are black and white spotted, the recessive phenotype. Calculate the frequency of the black allele (B) and the spotted allele (b) in the population, as well as the frequency of each genotype (BB, Bb, and bb) in the population.
What are the basic components of a cell?
If 9% of an African population is born with a severe form of sickle-cell anemia (ss), what percentage of the population will be more resistant to malaria because they are heterozygous (Ss) for the sickle-cell gene?
DIHYBRID CROSSES WITH INCOMPLETE DOMINANCE In cattle, polled is dominant to horned, and roan is the result of the heterozygous condition of the genes for red and white. What proportion of the offspring of a red, heterozygous polled bull and a roan, horned cow would be expected to be roan and horned? 25% SEX LINKAGE
The development of DNA and genetic analysis has opened up a whole new branch of biological investigation: molecular phylogeny. DNA analysis has been used to reclassify a great number of organisms. These ultra-sensitive techniques have been able to reveal previously imperceptible relationships between both living and extinct orga
I need to be able to list the work and list the expected phenotypic ratios for the following crosses: A. If a red cow is bred with a white bull, all offspring are roan, which have red and white hairs intermixed on the hide. I know this is an example of co-dominance, but what are the results of roan x roan? B. If solid x sp
If a rabbit breeder crossed a pure-bred white normal-coated male with a pure-bred black Havana female with satin coat and all the offspring were Havana black with normal coats. Then he crossed two of the Havana blacks with normal coats in hopes of obtaining a satin black Havana rabbit. What would be the likelihood of this
There is an international conference that has been called to promote research in biomimicry that will have applications in genetic engineering and in biotechnology. The research and Development Corporation uses biomimicry techniques to look for antibiotics produced by fungi. You have been asked to present at conference. You
Identify and describe one or two structural and functional differences between prokaryotic and eukaryotic cells that you believe contribute to the ability of eukaryotic cells to form the specialized cells and structures found in multicellular organisms. While there are several differences between prokaryotic and eukaryotic cells
STUDY FIGURE 16-2. Then, in the space at the left, write the letter of the terms or phrase that correctly answers each question or best completes each statement. -The chromosome number of stage E is haploid is diploid is alike for all different species cannot be determined -The chromosome number of st
1. A short-tailed mutant of mouse was discovered. Multiple crosses of this mouse to normal mice produced 27 normal, long-talied mice and 25 short-tailed mice. A series of crosses among short tailed mice were made and 21 short-tailed mice and 11 long-tailed mice were produced. Determine which phenotype is dominant and explain
1) According to the Law of Segregation, in an organism with the genotype AaBb what types of gametes will be formed? AB Ab aB ab 2) In garden peas, the allele for tall plants is dominant over the allele for short plants. A true-breeding tall plant is crossed with a short plant and one of their offspring is self-pollina

In a particular random mating population, the frequency of the O allele of the ABO blood group system is .6, the frequency of A is .3, and the frequency of B is .1. a) If a type O man and a type A woman produce a child, what is the probability it will be type O? b) If their first child is type O, what is the probability t
Kruppel and giant are 2 gap genes in drosophila for which the maternal effect gene bicoid serves as a transcriptional activator. Bicoid protein is present in an concentration gradient in the drosophila embryo, with the highest levels at the anterior end and progressively lower levels as one moves toward the posterior pole. a)
Early in the last century, English physician Archibald Garrod noticed that about half the albinos he saw in the course of his practice were the children of first cousins who had married each other. In almost all of the cases of albinism that he saw, whether or not the parents were related to each other, both of the parents were
So we are 98% genetically the same as apes. How do we know this, how is this possible, and what theories/laws does this support?
What is the sequence of events that takes place to go from gene to protein. I know there is a set of nucleic acids involved in this process. Identify these nucleic acids and explain their function in the process.
I am reading that sickle-cell anemia is a disease that is genetically prevalent in populations of African and middle eastern decent. How is it that a parent can have the disease and not the offspring and vice versa? Can you provide simple to understand websites for me to continue research on this topic?
Biotechnology and genetic engineering is changing rapidly. Do you think this pace is safe? Why or why not? What are your thoughts on cloning, genetic screening and manipulation? Can you explain your stand briefly and also provide me with a couple of references that I can use for better understanding? I need websites and verbiag

Briefly describe the purpose of the following features found in all or many plasmid cloning vectors. a) origin of replication (ori) b) multiple cloning site (polylinker) c) antibiotic resistane gene
In order to study the function of a gene you have cloned in the mouse, you decide to inactivate it using transgenic technology. Using recombinant DNA techniques, you construct a modified version of the cloned gene by introducing an antibiotic resistance gene into middle of it. Into what kind of cells you will need to introduc
