Is there anyone on here that has good knowledge of genetics? I'm working on a few exercises I have to do for genetics class with my friend and would love some input.
Here are the problems:
<insert school name here> scientists recently discovered a rare breed of cat. One has green fur, one has red fur, and one has purple fur. The brilliant <school name> scientists discovered that this trait was due to only one gene with multiple alleles. They did 3 crosses, and each of the crosses involved a different parent cats.
CROSS............................................. .....................RESULT
Purple and Green ................................50% purple, 25% red, 25% green
Green and Red............................................ 50% green, 50% red
Red and Purple ............................................50% purple, 50% green
Which color is recessive, which is somewhat dominant, and which is truly dominant?
What are the genotypes of the parents of the 3 crosses?
Scientists studying IQ discovered that genes affect IQ equally. Further studies showed the following:
iiqq=IQ of 50
Iiqq=IQ of 75
IiQq=IQ of 100
IIQq=125
IIQQ=150
This pattern is an example of _________
If a person with IiQq crossed with an IIQq person, what would the phenotypic result be (IQ)?
Punk rock hair has now been found to be genetic, and an example of incomplete dominance. One parent punk rocker has blue hair, and another has red hair. What would the phenotypes of the Fsubscript1 generation be? What would the phenotypes of the Fsubscript2 generation be?
Any help would be greatly appreciated [
] While I do have some ideas, somethings just aren't working...
