Question

In guinea pigs, dark hair (D) is dominant over light hair (d) and curly hair (C) is dominant over smooth hair (c). Complete a dihybrid cross for parents with the genotypes: DdCc × DdCc and answer the following in complete sentences.

Describe how you would set up a Punnett square for this cross.
List the likelihood of each possible offspring genotype.
List the likelihood of each possible offspring phenotype.

Answer 1

if you copy and paste off yahoo ill know

Answer 2

http://bit.ly/PVqgcu That is the punnet square you want, just change the letters around.

Genotypes are the "genes" of the offspring, while phenotypes are the "ph"ysical characteristics.

Genotypes:
DDCC (1/16) - Dark Curly
DDCc (2/16) - Dark Curly
DdCC (2/16) - Dark Curly
DdCc (4/16) - Dark Curly
DDcc (1/16) - Dark Smooth
Ddcc (2/16) - Dark Smooth
ddCC (1/16) - Light Curly
ddCc (2/16) - Light Curly
ddcc (1/16) - Light Smooth

You can figure out the phenotypes, just add the fractions of the same physical features together.

Answer 3

LOST!!!!

Answer 4

What do you mean? What you you confused about?

Answer 5

how would you set up a punnet square

Answer 6

You know how to do quadratics in math, right? like ax^2+bx+c?

Answer 7

no

Answer 8

im in geomerty

Answer 9

going into algebra 2

Answer 10

im in 9th grade

Answer 11

hmmm... did you take algebra 1?

Answer 12

yes

Answer 13

but i barely passed same with geometry

Answer 14

there you go! :) it was in algebra one! they look like : \[x ^{2}+x+1\]

Answer 15

Well, I'll start explaining. If you look at the link I gave you, the top side and the left side have letters on them. These are the "possible combinations" that you're going to use.

Answer 16

ok

Answer 17

How you get them is by starting with the DdCc. And we find our first value
