Which of the following is a structural polysaccharide?

The phenotype of vestigial (short) wings (vg) in Drosophila melanogaster is caused by a recessive mutant gene that independently assorts with a recessive gene for hairy (h ) body. Assume that a cross is made between a fly with normal wings (homozygous) and a hairy body and a fly with vestigial wings and normal body hair (homozygous). The wild-type F1 flies were crossed among each other to produce 1024 offspring. How many of the F2 flies would you expect to have normal wings and a hairy body?

Which of the following components is different between amino acids?

In a multicellular organism, different tissues that function together are grouped into: 

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   Would you expect to get a similar result if you had originally crossed a yellow-bodied female with a wild-type male?

 (4 points total – 2 of which will go towards extra credit): Discuss Van der Merwe’s framework for speech motor control. What each level represents and its utility for the ability to disentangle various disorders. Include examples of each.

Where is a capsule found in a bacterial cell?

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?
