Similarities in DNA and amino acid sequences of proteins between two different species may indicate Multiple Choice common ancestry. that the two species cannot be related through common descent. that members of the two species will look and function exactly alike. the two types of organisms in question are really members of a single species and not different ones.

common ancestry

Explanation

Common ancestry refers to the fact that two or more species have the same ancestor. Moreover, in genetics, sequence homology (either DNA or protein sequence homology) refers to common ancestry between different species/taxa (instead of sequence similarity, which may be caused by both convergent or divergent evolution). In bioinformatics, both local and global alignments of DNA/RNA/protein sequences can be used to determine sequence homology. Sequence homology due to common ancestry may be caused by three types of evolutionary events: 1-speciation (ortholog sequences), 2-duplication (paralog sequences), or 3-horizontal gene transfer (compared to speciation and duplication, horizontal gene transfer is an extremely rare evolutionary event).

the genotypes would be 50% bb and 50% bb

the phenotypes would be 50% brown and 50% white. hope this : )

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.
