Question

i dont understand this?

Answer 1

13. Complete the monohybrid cross below the example using the directions for completing the Punnett Square in the reading and the example below. Then, list the genotypic ratio and describe the offspring. Be sure to remember that the capital letter is dominant.

Example: A green pea plant (GG) is being crossed with a green pea plant (Gg) yellow is the recessive color.

G G

GG
GG

Gg
Gg

G genotype = 2 GG : 2 Gg : 0 gg


g phenotype = 4 green pea plants : 0 yellow pea plants




A green pea plant (Gg) is crossed with a yellow pea plant (gg). Complete the Punnett Square using THESE genotypes.















Genotype: ___ GG : ____ Gg : ____ gg

Phenotype: ____ green plants : ____ yellow plants

Answer 2

they have bin boxes were the gs r .

Answer 3

this is very comfussing

Answer 4

Oh, I can definitely help you with this. Let me just finish up with another student real quick, okay?

Answer 5

ok thx :)

Answer 6

Okay, I am here. :) Please give me just a moment to type this stuff up. :)

Answer 7

So your box looks like this, right? Just a little neater... :)

Answer 8

yes

Answer 9

Okay. This is called a Punnett square. This will help you find out what genes an organism will have and what it will look like, based on the genes the parent gives it. Punnett squares usually test for one gene (a monohybrid cross), (in this case color) but they can test for more than one at the same time. Does this make sense? If so, I can move on.

Answer 10

yes

Answer 11

Okay, great. :)

To figure out a Punnett square, you have to realize that everything is based on probability (yes, math). To get a punnett square filled out, we have to multiply the alleles together to figure out gene probability. But don't worry - it's not too hard once you get the knack of it. :) Here's the first one: Do you get this?

Answer 12

In that first box, I multiplied G * G to get GG
