In a genetic cross between aabbccddee and aabbccddee what fraction of the offspring will be homozygous dominant for all five gen
aniked [119]

Answer:

None

Explanation:

The desired homozygous dominant genotype is AABBCCDDEE. To have an offspring with genotype "AABBCCDDEE", at least one copy of the dominant alleles for the genetic loci should be present in either of the parent. However, both the parents are homozygous recessive for all the five mentioned genetic loci and therefore, cannot have a progeny with homozygous dominant genotype "AABBCCDDEE". All the progeny of a cross between the two parents each with genotype "aabbccddee" would have homozygous recessive for all the give loci.

aabbccddee x  aabbccddee =  All aabbccddee

How would you account for the fact that fossils of fish are not present in the older layers of rock?
Mademuasel [1]

Answer:

The fish did not yet exist when the old layers of rocks were deposited. In fact, animals with hard parts did not evolve until about 600 million years ago, which is only about 13% of the 4.5 billion year age of the Earth. Multicellular animals without hard parts left tracks in older sediments, but had no fossilize-able body parts.
