The user can, through a series of tabs, navigate multiple results pages, and also includes novel functionality, such as a dotplot graph viewer, modeling tools, an improved 3D alignment viewer and links to the database of structural similarities.

Heterozygous indicates two different genes for a hereditary characteristic. In this case, the man is heterozygous because he has one gene for brown hair B and one gene for red hair b.

The brown hair gene is dominant, so it is capitalized, and because it is dominant he has brown hair. Homozygous indicates two identical genes for a hereditary characteristic. In this case, the woman has two genes for red hair Cladogram lab.

The genes are in lower case since they are recessive.

She only has genes for red hair, so she has red hair. You can solve this type of problem by filling out a Punnett Square as shown below: Children with the genes BB will have brown hair, but none of the children have this combination of genes. Children with the genes bb will have red hair, and 2 out of every 4 children will have red hair.

Question 4 In the 21st century, worker bees in bee colonies have been abandoning their queens and are deserting their hives in record numbers. This issue became more commonly known when The National Agriculture Statistics Service reported in that only 2. There is no consensus among scientists as to what is causing Colony Collapse Disorder, though the USDA has undertaken a plan of action to stem the collapsing colonies involving several steps: The first findings from the USDA were published inand suggested factors such as pesticides, parasites, and pathogens may be possible causes, all of which have affected hives in Northern California.

To test her hypothesis she is planning to run an experiment. A The types of pesticides that are used in Napa Valley. B The types of parasites that are present in Napa Valley.

C The types of pathogens that are present in Napa Valley. In order to best support her argument that the pesticides are responsible for colony collapse, the researcher should expose the healthy bee colonies to the same pesticides used in Napa Valley.

If she uses the same pesticides, as well as a control, and the colony exposed to the pesticide does collapse, then her hypothesis is well supported. In order to convert Fahrenheit to Celsius, the following formula can be used: You may use your calculator.3.

Biologically, one could use anatomical features, behavior, or molecular similarities and differences in constructing a cladogram. Molecularly, one could look at the number of mutations in a .

Cladistics attempts to do for the entire history of life what genealogy does for the history of human families: to disentangle the relationships between all living beings.

What is a cladogram? It is a diagram that depicts evolutionary relationships among groups. It is based on PHYLOGENY, which is the study of evolutionary relationships. Sometimes a cladogram is called a phylogenetic tree (though technically, there are minor differences between the two).
