Phenotypic

... months, and I would appreciate some commentary. I recently learned about epistasis and genetic heterogeneity . Apparently, you can get similar phenotypic results from mutations in different genes that are part of the same biological pathway. To me, this seems similar to computer programs that ...

... to do Punnett: .... R .. r R . RR . Rr r . Rr . rr thus you see that F1 will be genotypically RR : Rr : rr - 1 : 2 : 1. It should be easy to make phenotypic ratio from that. F2 generation will be pretty hard, because one can combine all three of them for each parent.

... white flower colour (r). If these plants were allowed to self-pollinate and produced 1284 seeds, use a Punnett square to predict the genotypic and phenotypic rations for the F1 and F2 generations.

... recessive for plant size: a. What is the phenotype of this plant? b. If this plant was crossed to a dihybrid (heterozygote), what would be the phenotypic ratio of pod shape among the progeny? c. What would be the phenotypic ratio of plant size? d. What would be the phenotypic ratio of pod shape ...

... quite a bit. Even when the phenotype is variable, there's still an underlying genotype that could be affected by natural selection. In the case of phenotypic plasticity, it is the ability to change one's phenotype that is selected for when the environment is variable. This ability is linked to ...
