diversity of organisms

Question 1

morphological species concept

Answer 1

unique physical characteristics determine the species where an organism belongs

Question 2

sexual dimorphism

Answer 2

male and female of the same species look distinctly different

Question 3

biological species concept

Answer 3

if members of 2 different species interbreed, their offspring will be infertile
- mules

Question 4

what group cant biological species concept be applied to

Answer 4

asexually reproducing organisms

Question 5

number of different chromosomes

Answer 5

22 pairs of autosomes and 2 sex chromosomes = 46 in each diploid cell

Question 6

speciation

Answer 6

formation of a new species from the splitting of a former one because of reproductive isolation (physical or behavioral/timing) or a change in chromosome number due to non-disjunction

Question 7

karyotyping

Answer 7

a test to examine the chromosomes of an individual that involves isolating condensed chromosomes from actively dividing cells. can help identify genetic problems by pairing the matching chromosomes in a karyogram

Question 8

chromosomes are paired in karyotyping based on

Answer 8

size, banding patterns and centromere location

Question 9

what created chromosome 2 & evidence

Answer 9

the fusion of chromosomes 12 and 13 in the great ape karyotype

-genes match
-telomeric dna found at the suggested fusion region
-second centromere region that doesnt work

Question 10

telomeric dna

Answer 10

found at the ends of chromosomes to help protect the ends from damage

Question 11

genome

Answer 11

total genetic information of an organism

Question 12

genome sequencing

Answer 12

a slow process of determining the order of bases in an organism’s genetic code

Question 13

advantages of genome sequencing

Answer 13

comparing the genome of humans with other great apes

revision of current classification systems and seeing if reorganization is necessary

new possibilities for medicine (personalized treatment)
