The VNTR alleles analyzed in forensic DNA fingerprinting experiments are highly variable from individual to individual. How do the many VNTR alleles at a single locus differ from each other.
Two people, each homozygous ro autosomal recessive deafness-producing alleles have four children. Three are deaf. One can hear. Possible explanations for the appearance of the hearing child include
Human HLA genes (equivalent to MHC genes in mice) have many alleles, and no two individuals have identical alleles at all gene loci. Which of the following are consequences of this genetic diversity
In a lab experiment we examined the evolutionary effects effects of genetic stress: a harmful recessive mutation (nub E and nub X)that was experimentally introduced into a population of flies hundre
Now let's assume it is expressed in human. I wish to express the cDNA corresponding to this gene in order to determine its function. How would you construct an expression vector? Would you use the g
From the answer to (b) there will be two amino acids are repeated in the sequence although the condons in the mNRA are all different from each other. Using one of the repeated amino acids in the seq
Show a cross between 2 parents with yellow seeds, both of which are heterozygous. The square will be used to predict how many offspring with green seeds to expect among a population of 1200 offsprin
Punnett square for eye color in fruit flies for a cross between a white-eyed female and a red-eyed male. Red eye color is dominant. The eye color gene is carried on the X chromosome.
When a pure-breeding red flower snapdragon is crossed with a pure-breeding white flower snapdragon plant it produced plants with pink flowers. this is referred to as.
Explain the test - cross. I have to explain the usefullness of the test-cross. I had my paper written then was told I need to incorporate the Punnett square, monohybrid cross, dihybrid cross etc.
Down syndrome occurs once in approximately 700 live births. The vast majority of these cases are due to trisomy 21 resulting from a non-disjunction event.
In pigs, there are two loci which can influence skin color, genes A and B. Color ranges from roan (red) to sandy to white. Roan pigs have at least one dominant allele at both loci, sandy pigs have a
Manx cats are distinctive because they do not have tails, their front legs are shorter than the rear legs, and they often travel by hopping. These traits are are controlled by a single gene. Manx ca
Manx cats are distinctive because they do not have tails, their front legs are shorter than their rear legs and they often travel by hopping. These traits are controlled by a single gene. Manx cats
Which of the following statements helps to explain why many people carry abnormal genes than are affected by them.
Today, scientific advances are being made at an astounding rate, and nowhere is this more evident than in our understanding of the biology of heredity. Using DNA as a starting point, do you believe
If a woman is a carrier for hemophilia and has a child with a man who does not have hemophilia, what percentage of their sons would be expected to have hemophilia? What percentage of their daughters
In peas, color (yellow or green peas) and seed texture (smooth or wrinkled ) obey Mendelaian laws. Yellow is dominant over green, and smooth is dominant over wrinkled.
In a captive colony, he selects a male chipmunk with short ears. Without any additional information, would the geneticist know the genotype of that particular male chipmunk.
A colorblind woman marries a man with normal color vision. What percentage of their sons would be expected to be coloblind, what percentage of their daughters would be ecpected to be colorblind expl
A man with Type O blood has children with a woman who has Type AB blood. what blood types would represent the full range of possible phenotypes in children that the man and woman might have together
Consider the following hypothetical genetics information for cottontail rabbits: Ear length is controlled by one pair of co-dominant alleles (E = allele for long ears.
A population of rattlesnakes lives on a desert island. Some members of this population have a unique adaptation which protects them form parasites that reside in the sand.
Carnations exhibit "blended inheritance" (co-dominant or intermediate inheritance). 2 alleles for color R and R' produce red and white flowers, respectively.
Flower color in carnations is controlled by one pair of co-dominant alleles; red flowered carnations have the genotype RR, white flowered carnations have the genotype R'R', and heterozygous individu
