- Gene dosage is important for a number of genetic phenomenon. Name two and explain their relationship to the genotype and phenotype observed.Mutations in DNA that result in altered proteins can causehereditary diseases. Pedigree studies and genetic testing mayclarify the risk of disease. At the chromosome level, nondisjunctionduring meiosis can result in gametes with too few or too manychromosomes, most of which produce inviable offspring.Imprinting refers to inactivation of alleles depending on whichparent the alleles come from; offspring in whom imprinting occursappear haploid for the affected gene even though they are diploid. During spermatogenesis, is there any difference in outcome between first- and second-division nondisjunction?***18. Complete this flowchart to show how different alleles can result in different characteristics. In the DNA, different alleles of a gene have a different sequence of > different sequence of transcription > different sequence of in a protein translation > different structure and function of the protein (e.g. normal enzyme vs. defective enzyme) > different characteristics (e.g. normal color vs. albino) in
- One example of non-Mendelian inheritance is uniparental inheritance. Choose the definition of uniparental inheritance. One parent transmits all genetic information to all offspring. Two parents transmit combined genetic information to all offspring. Two parents transmit combined genetic information to half of their offspring. One parent transmits all genetic material to only half of the offspring. Select the examples of genetic material that are uniparentally inherited in sexually reproducing eukaryotes. nuclear DNA mitochondrial DNA plastid DNA endoplasmic reticulum DNAWhat describes a situation in which an allele's expression depends on the parent from which it was inherited? autosomal linkage chimerism genomic imprinting mosaicismA sex-influenced trait in humans is one that affects the length of the index finger. A "short" allele is dominant in males and recessive in females. Heterozygous males have an index finger that is significantly shorter than the ring finger. By comparison, the "long" allele is dominant in females and recessive in males. The gene affecting index finger length is located on an autosome. A woman with short index fingers has children with a man who has long index fingers. What are the following probabilities? (Assume that 50% of the offspring are male and 50% are female.) A. A daughter with long index fingers B. A daughter with short index fingers C. A son with sort index fingers
- A species of centipede has a haploid chromosome number of 2. Leg length is controlled by a single gene with two alleles: the long leg allele (L) is dominant to the short leg allele (l). Body coloration is controlled by a single gene with two alleles: the dark allele (D) is dominant to the light allele (d). Leg length and body coloration are encoded by genes on separate chromosomes. Assume the traits obey Mendel’s law of Independent Assortment.A species of centipede has a haploid chromosome number of 2.

Body coloration is controlled by a single gene with two alleles: the dark allele (D) is dominant to the light allele (d). Leg length and body coloration are encoded by genes on separate chromosomes. Assume the traits obey Mendel’s Law of Independent Assortment. a) A centipede that is homozygous for the recessive allele at both loci mates with a centipede that is homozygous for the dominant allele at both loci. They produce 100 offspring. What fraction of the offspring would you expect to have short legs and light body coloration? Show your calculations and reasoning. b) Two centipedes that are each heterozygous for both leg length and body coloration mate and produce 100 offspring.

Several loci are associated with the trait. One locus is associated with variable phenotypes of a trait. Environment plays minimal or no role in the final phenotype. Phenotype is determined by different environmental factors.
- Sex-specific imprinting distinguishes male and female genomes and is inherited in a parent-of-origin-specific manner. Such imprints are established in the germline during gametogenesis and remain intact throughout embryonic and postnatal development. Access the Imprinted Gene Catalogue website https://www.geneimprint.com/Links to an external site.. Click on “Search by Species Name” and then click on “Human.” Find 4 disorders that involve imprinting: 2 transmitted from the mother and 2 from the father, and use OMIM to describe the phenotypes (you may include images of phenotypes) and explain their underlying cause(s).
