im guessing D.? jkjk C.?

Answer 31

yea - C

Answer 32

okay cool

Answer 33

google phenotype

Answer 34

observable characteristics

Answer 35

you see :} --physical expression [brown hair, blue eyes, etc]

Answer 36

yea

Answer 37

heh

@dakotajade

Answer 40

a!

Answer 41

organism’s genetic composition is known as its
A. karyotype.
B. phenotype.
C. genotype.
D. gene.

Answer 42

sorry i left ;/

Answer 43

it's okieeee

Answer 44

physical = phenotype , so genetic should be genotype

Answer 45

yeah!

Answer 46

lol

Answer 47

hahah im done for the dayyyy

Answer 48

yay

Answer 49

hahah.
