A man of unknown genotype has type B blood, his wife has type A blood (also unknown genotype). List ALL the blood types possible
shtirl [24]

Answer:

AB, aB, Ab

Explanation:

Man has blood type B so could be BB (homozygous dominant) or could be Bb (heterozygous)

Woman has blood type A, so she could be AA (heterozygous dominant) or Aa (heterozygous)

Now, we need to make a separate cross for woman with AA, man with BB and we get children of all AB

Then we can make another cross for genotypes Aa and BB, and we get AB and aB

We can continue this for AA,Bb and for Aa,Bb

What conditions created the numerous fossils that make up the Burgess Shale?
grin007 [14]
The Burgess Shale is a rock formation that is known for having an abundance of soft bodied organisms preserved in shale. This formation is significant because it preserves organisms from the Cambrian Explosion. The Cambrian Explosion is a period in time that coincides with the Pre- Cambrian- Cambrian boundary around 542 million years ago. The period represents an unusually rapid radiation of organisms. 
Fossils of the Burgess Shale are thought to be well preserved because most were thought to be buried fairly rapidly and in conditions that had little or no oxygen. The rate of decomposition is slowed in these conditions so soft body parts of the organisms were preserved for millions of years in the mud-stone that eventually became lithified to shale. <span />
