Answer:

A) 1/256

Explanation:

Parent 1 : YyTtRrSs

Parent 2: YyTtRrSs

Probability of a YY offspring occurring in a cross between Yy and Yy = 1/4

Probability of a TT offspring occurring in a cross between Tt and Tt = 1/4

Probability of a RR offspring occurring in a cross between Rr and Rr = 1/4

Probability of a SS offspring occurring in a cross between Ss and Ss = 1/4

Total probability of YYTTRRSS =

1/4 * 1/4 * 1/4 * 1/4 = 1/256

Hence, 1/256 of offspring will be YYTTRRSS

What can be done to reduce the production of carbon dioxide?.

Phantasy [73]

Answer:

Probably not much.

We exhale carbon dioxide every second.

"Burn less trees." - thank you kaliliew16

Therefore, not much can be done.. We would have to all stop breathing to stop the flow of carbon dioxide, meaning we'd all die off quickly due to lack of oxygen.

hope it helps you!
