- The particular combination of alleles present in a given organism is referred to as a: Locus Gene Genotype Trait Phenotype________ are important to assess because they can modify gene expression. Environmental effects Environmental effects Genotypic variations Genotypic variations Phenotypic variationsPenetrance and expressivity are related but can be distinguished easily because: penetrance affects genotype; expressivity affects phenotype penetrance affects phenotype; expressivity affects genotype penetrance is a quantitative term; expressivity a qualitative term penetrance is a qualitative term; expressivity a quantitative term
- Write a short explanatory essay on the following statement: “Incases of genetically programmed phenotypic plasticity, naturalselection acts on the norm of reaction. Thus the norm of reactionas a whole—rather than any one phenotype—determines ifselection is positive or negative.”An important application of DNA fingerprinting is relationship testing. Persons who are related genetically have some bands or peaks in common. The number they share depends on the closeness of their genetic relationship. For example, an offspring is expected to receive half of his or her minisatellites from one parent and the rest from the other. The diagram shown here schematically illustrates traditional DNA fingerprints of an offspring, mother, and two potential fathers. In paternity testing, the offspring’s DNA fingerprint is first compared with that of the mother. The bands that the offspring have in common with the mother are depicted in purple. The bands that are not similar between the offspring and the mother must have been inherited from the father. These bands are depicted in red. Which male could be the father?Hi, I'm having some trouble with this practice problem from my study guide. If anyone can explain it it would be very helpful! Brindle coloration is a black and brown striping pattern in some dogs. This fur coloration is controlled by different alleles at a single autosomal locus. There are three alleles, KB, kbr and ky. The KB allele is dominant over the other two alleles and produces a solid black color. The allele kbr produces the brindle color pattern and is dominant over the ky allele, which produces yellow fur. Give the genotypes of the parents and offspring in each cross. P: black X yellow; F1: ½ brindle and ½ black P: black X brindle; F1: ½ black, ¼ brindle and ¼ yellow P: brindle X yellow; F1: 100% brindle
- Pedigree Analysis Is a Basic Method in Human Genetics Pedigree analysis permits all of the following except: a. an orderly presentation of family information b. the determination of whether a trait is genetic c. the determination of whether a trait is dominant or recessive d. an understanding of which gene is involved in a heritable disorder e. the determination of whether a trait is sex-linked or autosomalA geneticist is studying memory recall and is trying to locate specific genes that have varying effects on a given phenotype (physical trait) in the study subjects. These locations of these genes are referred to as: Group of answer choices Genomic spatial identifications Epigenetic regulators Evocative response indicators Quantitative trait lociExamples of codominance include ABO blood type and coat color in cattle. In short horn cattle coat color pattern is determined by two alleles (CR = red; CW = white) that are both equally expressed. CRCW cattle are roan (red and white patches); therefore, both alleles affect the phenotype equally. The ABO system of blood typing exhibits codominance in humans. There are 3 alleles for the gene that determine ABO blood type (IA and IB are codominant alleles; allelei is recessive to alleles IA and IB). IAIA and I^i are type A; I®I® and IPi are type B; I^IB is type AB; ii is type O Practice Problem 4: 4a. If a man with blood type O marries a woman that is blood type AB, what are the predicted genotypes and phenotypes of their children? 4b. If a man with blood type A (I^i) marries a woman with blood type AB, what are the predicted genotypes and phenotypes of their children?
- Gene dosage is important for a number of genetic phenomenon. Name two and explain their relationship to the genotype and phenotype observed.What does it mean when an individual is found to be “homozygous” at a DNA profiling locus? They have three alleles at the locus They got different alleles from their mother and father They got the same alleles from their mother and father Their children got two alleles from them Their children got no alleles from themMatch the following : Genetic testing Genetic screening Genetic screening programs Genetic screening opportunities A test with high senstivity A test with high specificity predictive tests Pre- symptomatic tests Pre dispositional test involves testing individuals for the genetic change underlying a condition for which there is no evidence. can show that an individual is more likely than others to develop a specified condition. indicate the presence of a causative genotype but the onset of signs and symptoms is not certain. are offered as part of our public health service. do not include conditions that show incomplete penetrance. is performed cases where the onset of signs and symptoms is considered inevitable. involves testing individuals for the genetic change underlying a condition for which there is evidence. has a low false positive rate has a low false negative rate
