1) A green pea plant (Gg) is crossed with a yellow pea plant (gg).

1) What is the pure-breeding (or true-breeding) strain or organism?

5. A woman with type AB blood marries a man with type homozygous type B blood. What are the phenotype and genotype ratios of the offspring? 6. Hemophilia is a sex linked recessive trait. If a carrier woman marries a normal man. The couple gives birth to a boy. What are the chances that this child will have hemophilia? Make sure use XX or XY here) 7. The height of a certain plant is a result of polygenic inheritance involving two pairs of genes. Draw a Punnett square to show the result of a cross between a tall (AABB) plant and a short (aabbi. What is the phenotype ratio? 8. What is a mutation? 9. What is sickle cell anemia? 10. What is hemophilia? 11. What is a pedigree? 12. Draw a pedigree to represent the following. Shaded symbols should represent individuals with hemophilia: A man with hemophilia marries a normal woman. They have 3 children, two normal boys and a girl who is a carrier. The girl marries a normal man and they have two boys and two girls. One of the girls is a carrier…

Can you draw punnet square for F1 and F2 for this cross

Additional problems (Chapter 4 (Extension of Mendelian Inheritance): 1. In rabbits, coloration of the fur depends on alleles of the gene c. From information given in the chapter, what phenotypes and proportions would be expected from the following crosses: a) CC X cc b) Cc x Cc c) Cc x Ccch d) cc x cc 2. From the information given in the chapter about the ABO blood types, what phenotypes and ratios are expected from the following matings: a) type AB x type O b) Type AB x type B individual whose mother is type O c) Type O x Type A individual whose father is type O d) Type Ox type O 3. A woman with type AB blood type gave birth to a baby with type B blood. Two different men claim to be the father. One has type A blood and the other type B blood. Can the genetic evidence decide in favor of either? 4. You have been studying a trait that seems to be present in every generation within a particular family. Further, you have observed that every affected offspring has at least affected parent…

Explain the term out-crossing.

1. Hemophilia is due to a sex-linked gene. It is recessive and found on the X chromosome. A woman who is a carrier for hemophilia marries a normal man. What will be the possible phenotypes of their children? Use a punnet square. 2. A phenotypically normal man, who has a hemophiliac brother, marries a normal woman, who is not a carrier. What is the probability that any of their children will be hemophiliac? Use a punnet square. 3. Color-blindness is an X-linked, recessive trait. If a normal-sighted woman, whose father was color-blind, marries a colorblind man, what is the probability that they will have a son who is color-blind? Use a punnet square. 4. A man and woman, both of normal vision, have:  1) a color-blind son (#1) who has a daughter of normal vision  2) a daughter (#1) of normal vision who has one color-blind son and one normal vision son  3) another daughter (#2) of normal vision who has five sons, all with normal vision  What are the probable genotypes of the…

In a pop, 1/10 men has Hemophilia B. HWE conditions are met, what is the incidence of Hemophilia B between women?
