The second tRNA to attach to the mRNA will occupy the __________ of the ribosome.

The only haploid cells in animals are:

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 large 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 F2 females?

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