problem # 1 In four o'clock plant , R is the allele for red color and N is allele for white color . Two pink flowered four o'clock plants were crossed . Show the possible outcome of the cross between two pink flowered four o'clock plants by using the punnett square .Problem # 2Now, another cross was made involving a red flowered four o'clock plant and pink flowered four o'clock plant .Using the punnett square , show the possible outcome .Guide Questions :1.How many types of gametes will each parent produce in problem no.1 ? In problem no.2 ?2.What is the phenotype of a heterozygous four o'clock flower ?3.What are the possible phenotypes of the offspring from the cross of the parental plants in problem no.1 ? In problem no.2 ?4.What are the possible genotypes of the offspring from the cross of the parental plants in problem no.1 ? In problem no.2 ?

1.problem no.1-two types of gametes for each parent
problem 2. one parent will have one type of gamete and the other two types of gametes since their genotypes are RR RN
2.Pink flowers
3.prob 1-pink,red flowers
prob 2- red , pink , white
4. prob 1 - RR, RN ,NN
prob 2-RR ,RN

Here are the answers:
Problem#1: The possible outcome between two pink flowered four o'clock plants is 25% Red, 25% White and 50% Pink

Problem#2 The possible outcome between a red and a pink flowered four o'clock plant is 50%Red , 50% white.

Answers to Guide questions:
1) there is only 1 type of gamete will produce
2)None
3)The possible phenotypes of the offsprings is
Red, white, pink
4) Red and pink
5) 25% red, 25% white 50% pink
6) 50%red 50% pink

hope this helps! :))
