If one parent has the pure A blood type (both alleles are A) is with genotype AA The other parent has the pure B blood type (both alleles are B) is with genotype BB
Crossing these two: AB AB AB AB
<span>which means that all of the children will have AB blood type (phenotype). This happens because of the codominance. The A and B alleles are codominant and therefore, if an A is inherited from one parent and a B from the other, the phenotype will be AB.</span>
<span>Lamarck believed that organisms could acquire characteristics during their lifetime, that they could pass down to their offspring, but Darwin did not believe these traits could be passed down. Darwin proved that the species adapted to their environment through natural selection. Meaning only the one that could adapt to the changes would survive. </span>
Answer: 1. founder effect
2. evolution
3. natural selection
4. species
5. geographically isolated
Explanation: Good luck! :D
All forms of RNA are intermediate molecules that are fabricated within DNA to perform cellular functions.
mRNA - messenger RNA carries selected portions of DNA used to fabricate polypeptides used to fabricate amino acids for protein.
tRNA - transfer RNA is comprised of select genetic code and transfers amino acids to ribosomes for assembly
rRNA - ribosomal RNA is comprised of select genetic code and makes the ribosomes
RNA is highly mutatable, highly reactive, non-reproductive, and highly specialized metabolically, and consequently totally unsuitable for consideration of any pre-DNA senario being posited for the origin of life.
The answer is 1 astronomical unit
