Open Question: General biology: genetic inheritance?

17:30 Publicado por Flechado16

1) In a typical cross where a parent with a completely dominant trait is mated with a parent exhibiting a completely recessive trait, what is the expected genotypic outcome and allelic frequency for the F1 progeny? Give an example.

2) In a typical cross where hybrid F1 parents are mated, what is the expected genotypic outcome and allelic frequency of the F2 progeny? Give an example.

3) For the F2 progeny produced from a typical F1 hybrid mating, how many totally recessive individuals would be produced if the progeny total population is six offspring? What if the progeny population was 20? 50? 1,000?

4) Excluding factors such as sex-linked genes, incomplete dominance or epistasis, etc., will the above cross results vary if different organisms are used, such as dogs or tulips? Why or why not?

5) How will factors such as sex-linked genes, incomplete dominance, or epistasis, etc., affect the expected outcomes that were investigated above?

I am finishing up a report and these are the only questions I have left and I am stumped. Any help would be greatly appreciated. THANK YOU!
