Scenario 2: A scientist is studying a population of lizards in a local pond. The lizards are normally a murky brown color and blend in with the water and banks of the pond to avoid predators. Recently the scientist has noticed lizards that are born white instead of the normal brown color. He does genetic testing on both types of lizards and determines that the brown coloring should be the only color option for that type of lizard. Select the best explanation for the albino lizards. A Brown color is recessive to white. B The DNA mutated to change the color brown to white. Someone painted the lizards white.

IN TRANSYLVANIA, SOME PEOPLE EXHIBIT TWO UNUSUAL TRAITS IN WHICH THEY HAVE VERY LONG FRONT TEETH AND THE INABILITY TO BE AWAKE WHEN THE SUN IS UP. BOTH OF THESE TRAITS APPEAR TO BE RECESSIVE. IF A WOMAN WHO IS HETEROZYGOUS FOR TEETH AND HOMOZYGOUS NORMAL FOR BEING IN THE SUN MARRIES A MAN WHO HAS BOTH THESE TRAITS, WHAT COULD BE THE PHENOTYPES AND GENOTYPES OF THEIR CHILDREN? USE A PUNNET SQUARE AND SHOW ALL WORK. LIST THE RATIOS FOR THE GENOTYPES AND PHENOTYPES.

Labrador retrievers are commonly black, brown, or yellow. Two different genes determine coat color in Labrador retrievers. The B gene determines pigment color (B is black, bb is brown). The E gene determines whether the pigment can be deposited in the hair shaft: ee prevents any pigment from being deposited, resulting in yellow dogs. You want to breed Labrador retrievers, and you cross a true-breeding brown Labrador retriever to a true-breeding yellow Labrador retriever. All 15 of the F1 puppies are black. After the puppies grow up, you cross two of the F1 black dogs together. In the F2 generation you get 8 black puppies, 4 yellow puppies, and 3 brown puppies. Part 1 What is/are the possible genotype(s) of the true-breeding brown lab in the P generation? O bbEE Brown bbee O bbEe Could be either answer bbEE or bbEe Part 2 What is/are the possible genotype(s) of the true-breeding yellow lab in the P generation? Obbee Bbee BBee Could be either bbee or Bbee. O Could be either Bbee or BBee.…

PLEASE DO BAR GRAPHS BASED ON DATA: Procedure: Assuming both parents carry three tall genes and three short genes, you will model the inheritance of height for ten different offspring. Flip a coin six times to determine how many tall and short genes the child inherits. Heads represents a tall gene and tails represents a short gene. Record all of your data along with the class data in the tables below   Data: Table 1: Group results   Flip (Your Group)          1              2     3     4    5 Number of tails  0  1  2  3  4 Number of heads  6  5  4  3  2   Table 1: continued    Flip (Your Group)    6    7      8     9    10 Number of tails  5  6  3  2  1 Number of heads  1  0  3  4  5   Table 2: Group and class results Flip  Situation 0 T 6 H 1 T  5 H 2 T  4 H 3 T  3 H 4 T  2 H 5 T  1 H 6 T  0 H Your Group Total  1  3  6  10  9  5  1 Class Total    0…

Nancy Jones is a doctor who specializes in genetic diseases. For many years she has been studying populations of people who have Huntington’s disease. Dr. Jones has a special interest in Huntington’s disease because her mother died of this disease after many years living in a wheelchair. Dr. Jones’s father does not appear to have the disease. She has developed a test that can detect the dominant Huntington’s gene before symptoms appear and she has performed this test on many people. This test involves mapping a person’s genome to determine if the dominant Huntington’s gene is present. Dr. Jones is unsure if she should take the test herself as it will not prevent the disease from developing, only give the person advanced warning of the disease. Nancy Jones has a sister. Draw a pedigree chart that maps the disease through this family. Make sure to indicate those family members that have the disease, those that do not have the disease and those whose status is unknown.  If you were Nancy…

Human hair color ranges from black to many shades of brown to blonde. What can you correctly conclude from this information? A Human hair color is controlled by a single gene. B Human hair color is controlled by environmental factors rather than genes. C Human hair color is controlled by more than one gene. D Black hair is dominant to blonde hair. Answer is C? Can you help me to explain to me step by step?

Human blood type is regulated by 3 alleles (A,B,O). Four blood types are possible: A, B, AB, and O.  A woman who has blood type A has a son with blood type O. She sues Man #1, whom she claims to be the father, for child support.  Man #1 suspects he is not the only paternal candidate and requests blood-typing for Man #2. Based on the blood-typing results in the table below who could be the father? Man #1: Type B Man #2: Type O Man #1 only Man #2 only Man #1 or Man #2 Impossible for either, since the Mother has blood type A

The gene S determines the stripe color of a kind of snake.  It has two alleles which are codominant with each other: one allele (S1) causes red stripes, and the other (S2) causes white stripes.  What do you predict a heterozygous (S1S2) snake will look like? Select one: a. Assortment of pink, red, and white stripes b. All pink stripes c. No stripes d. Both red and white stripes
