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 # 2
Now, 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 .

Answers to Guide Questions:

Q1) How many types of gametes will each parent produce in problem no.1 ?

Let's first recall the gametes of Parent 1.

The gamete of the Pink four o'clock flower is: RN

  • The possible number of gametes that will be produced by crossing the parents will be 4.

In problem no.2 ?

Let's first recall the gametes of Parent 2.

The gamete of the Red four o'clock flower is: RR

The gamete of the Pink four o'clock flower is: RN

  • The possible number of gametes that will be produced by crossing the parents will be 4.

Q2) What is the phenotype of a heterozygous four o'clock flower?

As mentioned above the phenotypes of the RR flower is Red, the phenotypes of the RN flower is Pink.

Q3) What are the possible phenotypes of the offspring from the cross of the parental plants in problem no.1?

For problem 1,

The phenotypes of the possible offspring of the parental plants (Both Pink) would be as follows:

  • 50% Pink
  • 25% Red
  • 25% White

In problem no.2 ?

For problem 2,

The phenotypes of the possible offspring of the parental plants (Red and Pink) would be as follows:

  • 50% Pink
  • 50% Red

Q4) What are the possible genotypes of the offspring from the cross of the parental plants in problem no.1 ?

For problem 1,

The Genotypes of the possible offspring of the parental plants (Both Pink) would be as follows:

  • 50% RN
  • 25% RR
  • 25% NN

In problem no.2 ?

For problem 2,

The Genotypes of the possible offspring of the parental plants (Red and Pink) would be as follows:

  • 50% RN
  • 50% RR

The below is the Punnett square created for problem 1 and 2 for your reference
