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.

What is the most likely method by which a gene produces red eyes in fruit flies?

chemical in the cells of the eye
the gene codes for an enzyme that is red
a mutation changes the coding sequence of the gene so that it codes for a red
protein instead of a white protein
the gene codes for a chemical that is red in color
If you have a mutation in your skin cells from falling asleep in a tanning bed, how will this affect your offspring?
Question 10 options:
It will affect their entire body because their entire body grew out of the fertilized egg
It may affect them, depending on whether those particular skin cells are passed on to them
It will affect your offspring's skin cells only
It won't affect them because the mutation is not in a gamete
It won't affect them because mutations cannot be passed down to offspring
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 cell

- 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_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. This is an example of: A crazy waste of time A forward genetic screen A reverse genetic screenarrow_forwardCloning 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_forward

- What type of mutation is this? 1. Which type of mutation is responsible for new varia tions of a trait? Which type of mutation does not result in an abnormal amino acid sequece? Which type of mutation stops the translation of an mRNA molecule? 2. Sickle Cell Anemia Sickle cell anemia is the result of a type of mutation in the gene that codes for part of the hemoglobin molecule Hemoglobin carries oxygen in your red bloods cells. The mutation causes these red blood cells to become stife sickle-shaped when they release their oxygen. The sickled cells tend to get stuck in blood vessels, causing poin ond increased risk of stroke, blindness, damage to the heart & lungs, and other conditions.

For example, mutations in the RET gene can cause two different types of multiple endocrine neoplasias, familial medullary thyroid carcinoma, and Hirschsprung disease. How do you think mutations in a single gene can have such diverse effects?arrow_forward
