Question
Chapter 43, Problem 4S
Summary Introduction
To determine: The evaluation of control of genes that controls the development and these regulate the expression of various parts of the genome.
Introduction: The genes are the functional unit of DNA. They possess some specific functions to perform. The different sets of the gene regulate the expression of different parts of the body.

Who is Norman Borlaug?arrow_forwardYou want to make a phylogenetic tree of a group of three related species of lizards that live on an island. Their genome sequences are highly similar except for a gene that controls body size. In that region of the genome, one of the lizard species has one copy of the growth control gene (L1), the second species has a duplication of the growth control gene (L2) and the third species has three copies of the same gene (L3). The lizard species show an increase in size depending on how many copies of the growth control gene they have (L1 is smallest, L2 is medium-sized and L3 is largest). Is this enough information to determine the phylogenetic relationships between the species, and predict which of the species arrived on the island first (and is the ancestral species)? Yes, because the ancestral lizard genome probably had a single copy of the growth control gene and after arriving on the island it was duplicated, resulting in species L2, and then another duplication occurred resulting in…arrow_forward
- Dominguez et al. (2004) suggest that by studying genes that determine growth and tissue specification in the eye of Drosophila, much can be learned about human eye development. (a) What evidence suggests that genetic eye determinants in Drosophila are also found in humans? Include a discussion of orthologous genes in your answer. (b) What evidence indicates that the eyeless gene is part of a developmental network?arrow_forwardIn addition to physical traits, gene sequences can be used when comparing related species. Instead of looking for the presence or absence of a specific gene, you would look at the percent similarity between the same gene in two or more species. Therefore, it is important to select a gene that contains a similar DNA gene sequence in each of the species being compared. Certain genes are involved in processes that are required for basic cellular function. As these processes are critical to cell function, the genes that regulate them are highly conserved, meaning that they have remained essentially unchanged over time. Glycolysis is one such process that is critical for cellular metabolism. Glycolysis involves converting glucose into pyruvate in order to generate ATP, the energy currency of the cell. Because glycolysis is an essential process for all species, the genes involved are therefore highly conserved. You will be looking at similarities among different taxa of the highly conserved…arrow_forwardWhich of the following is the sequence in which the segmentation genes act? a.
