What offspring can be expected from crossing a heterozygote with a white one? Show all steps.What does it mean for an allele to be dominant? (Hint: it doesn’t just have to do with the fact it’s capitalized).HW: IP: EOC Grab Bag

6. Some alleles are neither dominant nor recessive, and many traits are controlled by multiple alleles or multiple genes.

9. Some alleles are neither dominant nor recessive, and many traits are controlled by multiple alleles or multiple genes.
10. Incomplete dominance is a pattern of inheritance in which neither allele is completely dominant over the other. The heterozygous phenotype is somewhere in between the two homozygous phenotypes.we CAN use two different letters to represent the different allelesgenotype:phenotype: R = redW = whiteRRWWRWredpinkwhiteIn incomplete dominance, there are always 3 phenotypes. One is in the middle of the other two.Red + White = pINCINComplete dominance!
11. B = blackW = whiteCoat color in mice exhibits incomplete dominance.BB?black
12. B = blackW = whiteCoat color in mice exhibits incomplete dominance.WW?white
13. B = blackW = whiteCoat color in mice exhibits incomplete dominance.BW?gray
14. R = redW = whiteRR?redFlowers exhibit incomplete dominance for petal color.
15. R = redW = whiteWW?whiteFlowers exhibit incomplete dominance for petal color.
16. R = redW = whiteRW?pinkFlowers exhibit incomplete dominance for petal color.
17. T = tallS = shortTT?tallHuman height follows a pattern of incomplete dominance.
18. T = tallS = shortSS?shortHuman height follows a pattern of incomplete dominance.
19. T = tallS = shortTS?mediumheight Human height follows a pattern of incomplete dominance.
20. Scale color in fish is controlled by two incompletely dominant alleles. The homozygotes are blue and yellow. What are the genotypes for blue, yellow, and green fish?blue – yellow – green –
21. Wing color in birds is controlled by two incompletely dominant alleles. The homozygotes are blue and red. What are the genotypes for blue, red, and purple birds?blue – red – purple –
22. Tooth number in Zorgs is controlled by two incompletely dominant alleles. The homozygotes have 2 and 4 teeth. What are all possible genotypes of Zorgs?2 teeth – 4 teeth – ?? teeth –
23. Coat color in mice is incompletely dominant. Yellow and white-colored mice are homozygous, while cream-colored mice are heterozygous. If two cream-colored mice mate, what phenotypic ratio can we expect of their offspring?Solving an Incomplete Dominance ProblemYWYWYWWYYWYW1. Read the problem. Underline the known alleles. Identify the type of inheritance as incomplete dominance. 3. Circle and/or write down the genotypes of the parents. 4. Set up and solve Punnett Square. 5. Highlight and answer what the question is asking. 2. Choose a letter to represent each allele in the problem. Y = yellow; W = whiteparents: YW x YWyellow = white= cream = 1/4 = 1/4 = 2/4 = 25%50%25%
24. What type of inheritance? (Complete or Incomplete Dominance)Tall pea plants are crossed with short pea plants. All the offspring are tall. How do you know what type of inheritance it is?
25. What type of inheritance? (Complete or Incomplete Dominance)Having 10 fingers is dominant to having 12 fingers. A woman with 12 fingers has a child with a normal man and all their children have 10 fingers. How do you know what type of inheritance it is?
26. What type of inheritance? (Complete or Incomplete Dominance)A blue butterfly mates with a yellow butterfly. All their children are green. How do you know what type of inheritance it is?
27. What type of inheritance? (Complete or Incomplete Dominance)You have a black horse and a white horse on your farm. They have babies, and they’re all gray.How do you know what type of inheritance it is?
28. What type of inheritance? (Complete or Incomplete Dominance)You have a black horse and a white horse on your farm. They have babies, and they’re all black.How do you know what type of inheritance it is?
