Draw a cell with 2n=4 chromosomes in anaphase II of meiosis. How is this different than anaphase of mitosis?
In chickens comb shape is controlled by a pair of interacting unlinked gene loci each with two alleles, R,r and P,p. These genes interact in such a way to give four possible phenotypes, as follows:
Walnut - requires one each of the dominant genes.
Rose - requires a R and homozygous recessive for the p gene.
Pea - requires a P and homozygous recessive for the r gene.
Single - requires fully homozygous recessive.
If two walnut comb chickens are mated and produce 1,000 offspring, and some of these 1,000 offspring are of the single combed variety. Please answer the following questions:
a.___ How many of rose comb phenotype would you expect in the 1,000 offspring?
A. 563, B. 438, C. 360, D. 188, E. 63
b.___ The evidence provided would result in the conclusion that the inheritance of comb form in chickens is a good example of a polygenic mode of inheritance.
True OR False
c.___ What would be the best way to describe the cross involved?
1. A true dihybrid cross…

A. Intron
B. Enhancer sequence
C. TATA box
D. 5’ cap

1.___ part of mature mRNA that is instrumental in binding to the ribosome
2.___ part of the coding strand promoter region where the transcription initiation complex will form
3.___Sequence found in the upstream section of eukaryotic DNA, sometimes at very great distances that can result in the increase of the initiation and therefore transcription of genes.
