Why are geneticists interested in mapping the genomic position of genes underlying phenotypic traits?
Homework Answers
Mapping the genomic position of the genes underlying a phenotypic trait is of interest of the geneticists because:
- It can provide information about whether the genetic loci control a phenotypic trait independently or by interaction with other loci and how is it changing through the course of time which can aid to know if a particular phenotype is evolving or not with time.
- It can help in the identification of the disease-associated genes as their expression will be always associated with a particular phenotype.
- To determine the complexity of the genetic architecture and expression pattern, underlying a particular phenotypic triat. For eg- Quantitative trai loci(QTL) are the ones which are involved in the increase in the expression of a particular phenotypic trait with the corresponding increase in the gene no., indicating that the effect of the gene expression can be additive.

1. What is often true about the relative rates of phenotypic evolution of sexually selected traits vs most other kinds of traits? 2. In the good genes model, why does a male trait have to be costly in order for the female preference to be maintained by natural selection? 3. Explain the Fisherian (runaway)model of sexual selection –what generates correlations between female preferences and male traits. What kind of experimental observation would support the model? 4. Explain the concept of...

Why would changes in the genes for transcription factors be expected to generate major phenotypic differences?...
Why would changes in the genes for transcription factors be expected to generate major phenotypic differences? They are extremely powerful genes. They can affect the expression of small numbers of other genes. Their gene products are remarkably stable. Their gene products normally denature more rapidly than other gene products. They can affect the expression of large numbers of other genes. Which enzyme, also responsible for siRNA formation, carves miRNAs from their double-stranded, fold- back RNA precursor (pre-miRNA)? Dicer ribonuclease RNA...
