BIOLOGY HELP!

Post by notsosure » Wed Feb 21, 2007 1:30 pm

Hi,
I have 4 questions regarding Biology work.

1. Does a different chromosome number in two species represent a significant difference?

2. Chromosome 7 has an extra band at the top in chimpanzees; does this extra band affect the quantity of coding DNA? And does it make a significant difference in the species?

3. How can an individual with 22 pairs of autosomal chromosomes mate with an individual with 23 pairs of autosomal chromosomes?

4. Why are blood protein tests (for determining phylogenetic relationships) more accurate than other comparison tests, but less accurate than others? And what other tests would these include?

THANK YOU!

3. If she didn't tell him beforehand, then he might be tricked into doing it.

4. It's more accurate than Ms Cleo.
