6. Franklin the Farmer has been working on breeding a line of chickens with large, golden crests. In these chickens, omall (R) and golden (B) crests are dominant to large (r) and brown (b) crests. Hearing of his work, an old friend from University gave Franklin a new rooster as a gift. Unfortunately, this rooster lost its crest in a long-ago barnyard brawl, and they do not have any information about its parentage. Wanting to make the best of the situation, Franklin decides to cross this battle-scarred rooster (whom he names Logan) with Thel, a hen with a large, brown crest. Of their offspring, half have a large crest, half have a small crest, and all have brown crests. a. Give the genotype of Thel: b. Give the genotype of the gumete that Thel can produce: c. What are the genotypes of the offipring? Small, brown crested offspring: Large, brown crested offspring:.

You are excited to be entering the world of chinchilla breeding! At the most recent chinchilla pet event you purchased a lovely grey chinchilla with large ears. You do some research and learn that Grey is dominant to white (Gg), and large ears are dominant to small (Ee). Your chinchilla breeding mentor has many combinations of chinchillas and he gives you a one-time offer to breed with any of this chinchilla! List all of the possible genotypes for your chinchilla: How could you determine which of these is the genotype of your chinchilla? How do we call this type of mating?

What are the possible gametes resulting from your offspring? What is the mate's genotype for eye shape and feet colour?
Part B 1. For the remaining characteristics, you will be looking at homozygous and heterozygous traits. Each trait will be determined to be homozygous recessive, homozygous dominant, or hetero- zygous. Letters representing the alleles will be given to you; the uppercase letter is always dominant and the lowercase letter is always recessive. If both dice rolled are even numbers, it indicates homozygous dominant alleles; if both are odd, it indicates homozygous recessive alleles; if one is odd and the other even, it indicates heterozygous alleles. 2. Eyebrows: Use the alleles "A" and "a" for this trait. Two separate brows are the dominant trait, whereas the unibrow (or one continuous brow) is recessive. 3. Eye shape: Use the alleles "R" and "r" for this trait. Round eyes are the dominant trait; almond shaped eyes are recessive. 4. Hitchhiker's thumb: Use the alleles "H" and "h" for this trait. Straight thumbs are dominant; Hitchhiker's thumbs (the curving upward of the thumb) are…

1. Honeybee workers undergo a resistant behavioral pattern called hygienic behavior. Susceptible worker genotypes failed to remove the diseased larvae, so that the disease spread easily throughout the honeybee colony. a) When inbred lines of resistant genotypes were crossed with inbred lines of susceptible genotypes, the F1 worker bees showed unhygienic behavior.Is hygienic behavior dominant or recessive in these bees? Why?

7. While Squidward's family boasts about being a purebred line for dominant light blue skin color, they are also purebred for a less distinguished trait: the recessive trait of baldness. Lack of hair causes Squidward some self-esteem issues that he does not want his children to face. He would like to ensure that his offspring have hair AND with his blue skin color. What traits should he look for in a bride? A. Must she have hair? Explain. Squidward Traits: Skin Color B. Must she be blue? Explain. Blue = B, Green = b Hair Hair = H, Bald =h C. Squidward has found a potential bride prospect with the green squid Octavia. While Octavia has does not. Determine the chances of their child being blue and having hair. hair, her father Squidward's Genotype Octavia's Genotype = D. Use the genotypes in above to complete the Punnett square below and then answer the questions. E. Answer these questions based on your Punnett square. For which traits, if any, is it possible for their offspring to be…
Frieda breeds her black rooster with Elsie’s white hen. The offspring are all evenly speckled black and white. Elsie keeps all the chicks and adds them to her flock of white chickens. “I want to breed chickens that look like Dalmation dogs: mostly white, but with some black speckles,” says Elsie. Will Elsie be able to do this? Use Punnett squares to explain your answer.
35. Mr. Gascon is heterozygous for type A and Mrs. Gascon is type B. They have three children named Lesly, Jemima ard Wenchel. Lesly is type B. Jemima is type AB and Wenchel is type A. Based on the information, which child is adopted? A. Lesly B. Jemima 36. How is sex limited and sex influenced traits differ? C. Wenchel D.cannot be determined A. Sex- limited traits are those that are expressed exclusively in one sex while sex-influenced traits are expressed in both sexes but more frequently in one than in the other seX. B. Sex- limited traits occurs when the phenotype of the offspring is somewhere in between the phenotypes of both parents while sex- influenced traits are found only in one parent. C.Sex- limited traits are found on X and Y chromosomes while sex- influenced traits are found on the X chromosome only. D. Sex- limited traits occur only in males while sex-influenced traits occur only in females. 37. An extra finger in humans is rare but is due to a dominant gene. When one…

2 (a) The trait of hen- versus cock-feathering is a sex-limited trait controlled by a single gene. HH and Hh males always exhibit the hen-featuring trait. Only hh males show the cock-feathering trait. Starting with two heterozygous fowls that are hen- feathered, describe how you would obtain a true-breeding line that always produces cock-feathered males. [Ciri berhulu avam hatin
