wildsunflower2 Posted September 15, 2005 Report Share Posted September 15, 2005 I'm having a little trouble figuring this out, can anybody help me understand how to do this? If A is dominant to a, in the cross between Aa x aa, what percentage of individuals will have the A phenotype? What are all the possible genotypes?

UncleAl Posted September 15, 2005 Report Share Posted September 15, 2005 a | a----|------|------- A | |----|------|------- a | |----|------|------- If you don't crack your textbook you deserve to fail. Your textbook is probably political crap anyway, and your teacher (no, instructor; no, educator!) is a certified idiot. Look up "autodidact." Those who can, do.Those who cannot, teach.Those who cannot teach, teach teachers.Those who cannot teach teachers get government grants.Those who cannot get government grants consult.Those who cannot consult become political appointees.Those who fail as political appointees become industrial managers.

wildsunflower2 Posted September 15, 2005 Author Report Share Posted September 15, 2005 When I do the punnett square I get that 50% would have the dominant A phenotype and the possible genotypes would be Aa, aa, Aa, aa. Is this correct? I don't want the answer if it's not, I will just run through the steps again. Thanks Quote Link to comment Share on other sites More sharing options...
nkt Posted September 15, 2005 Report Share Posted September 15, 2005 Those who can, do.Those who cannot, teach.Those who cannot teach, teach teachers.Those who cannot teach teachers get government grants.Those who cannot get government grants consult.Those who cannot consult become political appointees.Those who fail as political appointees become industrial managers.And those who crack under the strain become counsellors. The OP reeks of someone who wants the answer to their GCSE Biology homework. Quote Link to comment Share on other sites More sharing options...
Qfwfq Posted September 16, 2005 Report Share Posted September 16, 2005 When I do the punnett square I get that 50% would have the dominant A phenotype and the possible genotypes would be Aa, aa, Aa, aa. Is this correct?Any reason to doubt this answer? Relax, and continue your homework. :xx: Also, pay no attention to those unnecessary remarks here! :eek2: Quote Link to comment Share on other sites More sharing options...
