Question

For each of the following scenarios, state the type of inheritance (20 points) and explain how you are able to discern this information (40 points). In addition, for each scenario, choose one other type of inheritance and explain why it does not apply (40 points). For example, if you have determined that a scenario falls under incomplete dominance, explain why it would not be co-dominance or complete dominance. All scenarios are imaginary, but based on the actual patterns of inheritance. 1) A blue alien and a green alien mate and produce 1,000 offspring that are all blue. Another alien couple who share the same genotyope and phenotype as the first couple also mate and produce 1,000 offspring, all of which are blue. Males and females from the two matings then mate with one another. Matings between the blue offspring produce 75% blue and 25% green offspring. 2) Fur length in the fuzzy wuzzy can be short, long or short-long. Short-long is marked by a pattern of alternating short and long strands of fur over the surface of the fuzzy wuzzy. Two short fuzzy wuzzies mate and produce all short fuzzy wuzzies. Two long fuzzy wuzzies mate and produce all long fuzzy wuzzies. Two short-longs mate and produce some shorts, some longs and some short-longs. 3) All Crayolians have ten hands with two fingers on each hand. In addition, all the fingers on each Crayolian are the same color, either red, white or pink. A pink-handed Crayolian mates with a white-handed Crayolian. Their offspring are 50% pink handed and 50% white handed.

Answer 1

One would have the recessive gene, but when mixed, they mixed the gene causing the 50%
AND
Well, obviously the blue color of the Alien is dominant, because when the green and blue aliens mate, their offspring are always blue.SHOW FULL ANSWER
