The diaphragm is in a dome shaped position___________; and is innervated by_____________.

Competition is central to the theory of evolution by natural selection. Why does competition occur?

If inheritance occurred through a blending mechanism, what would happen to variation in populations?    

If two parents who do not have cystic fibrosis have a child with cystic fibrosis, how would you describe the parents’ genotypes?

The trait of medium-sized leaves in iris is determined by the genetic condition PP’. Plants with large leaves are PP, while plants with small leaves are P’P’. A cross is made between two plants each with medium-sized leaves. They produce 80 seedlings. Of the 80 seedlings produced from this cross, how many would you expect to have small leaves?

A cross was made between homozygous wild-type female Drosophila and yellow-bodied male Drosophila. All of the resulting offspring were phenotypically wild type. Offspring of the F2 generation had the following phenotypes:         Sex               Phenotype           Number         male                wild                     96       male              yellow                   99       female             wild                   197   What is the genotype of the F1 females?

(Still putting the events of transcription in the correct order.) Finally…

What mechanism ensures that the daughter cells of meiosis are not genetically identical to  each other?

Legun’s blood type is AB and his sister’s blood type is O.  Which of the following is a possible genotype for the other parent?

The true-breeding plants Mendel worked with had what type of genotype?
