Question
Chapter 11, Problem 12SQ
Summary Introduction
To determine:
The name of such genes that produces a wing or leg in fruit fly and produces a big change if one gene is changed.
Introduction:
Homeotic genes are regulatory genes that determine where certain anatomical structures, such as leg or wing will develop in an organism during morphogenesis. These are the master gene of development and can act as switches for other genes.

Students have asked these similar questions
If you have a mutation in your skin cells from falling asleep in a tanning bed, how will this affect your offspring?
Group of answer choices
It won't affect them because mutations cannot be passed down to offspring
It will affect their entire body because their entire body grew out of the fertilized egg
It will affect your offspring's skin cells only
It may affect them, depending on whether those particular skin cells are passed on to them
It won't affect them because the mutation is not in a gamete

- Mutations in DNA may or may not result in a change in the phenotype of an organism. In which of the following situations will a mutation appear in the phenotype of an individual? The mutation occurs in an organism which is past reproductive age The genetic code for protein synthesis has not been altered in a gamete producing cell The mutation occurs in a body cell of the organism, resulting in cancer O The mutation results in a change in the amino acid sequence of the protein in a gamete producing cellarrow_forwardScientists look at thousands of mutagenized flies, one at a time, under a microscope. They are looking for flies that don't look like they have developed normally. They find a remarkable fly with an extra thorax and a complete extra set of wings.

- You are working in a lab that studies stickleback fish. These fish normally have three spines that occur on the back of the stickleback. One day you notice that a young stickleback has no spines on its back but instead has three spines growing out of the top of its head! Question: Briefly explain a study you could do to test if the difference between the mutant and wild type fish was due to a difference in the structural gene that makes the spines or due to a difference in gene expression.arrow_forwardYou are working in a lab that studies stickleback fish. These fish normally have three spines that occur on the back of the stickleback. One day you notice that a young stickleback has no spines on its back but instead has three spines growing out of the top of its head! (answer both questions) question 1: A mutation in what type of gene is probably the cause of this unusual situation? Why? question #2: would you expect the proteins that make the spines to be different in the mutant fish compared to a wildtype fish. Why or why not?arrow_forwardEvery cell contains all of the DNA for an organism. What controls when and how specific genes are expressed? Genes are not controlled, all genes are expressed all the time Gene expression is controlled by sequences in the DNA Gene expression is controlled by proteins Gene expression can be controlled by proteins and sequences in the DNA O 000arrow_forward
- Cloning is the process of creating genetically identical organisms. One simple method of cloning is called artificial embryo twinning. In this process, an early stage embryo is separated into two groups of cells. Each group of cells is then allowed to develop. The embryos are then implanted into the surrogate mother. Each embryo is genetically identical to the other. Some pregnancies in humans have a similar result. Explain how identical twins are formed. Compare and contrast the natural formation of identical twins to the artificial embryo twinning process. Explain how the formation of identical twins or the process of artificial embryo twinning differs from the formation of fraternal twins.arrow_forwardThe homeotic mutation Antennapedia causes mutant Drosophila to have legs in place of antennae and is a dominant gain-of-function mutation.

- Which of the following statements about mutations are true? * Mutations are always passed down to future generations. Mutations decrease the genetic diversity of organisms. Mutations occur only in somatic cells since they are diploid. Mutations are changes in the phosphate backbone of DNA which always have harmful effects. Mutations always cause a frameshift. Mutations can be harmful, neutral, or beneficial to the organism. Mutations are changes in the nucleotide sequence of a DNA molecule. Mutations may cause a change in the protein sequence resulting from the genetic code for that gene.
