Sagot :

Biology: Unit 1 Module 2

Activity 1: Phenotypes and Genotypes in Incomplete  Dominance

Q4. What are the possible genotypes of the offspring from the cross of the parental plants in problem no.1 and in problem no.2...

Answer:

For Problem 1:

The genotype of the resulting flower crossing two pink four o' clock flowers are as follows:

  • The genotype of the two RED four o'clock flowers are both RW.
  • Crossing RW x RW will result to a genotype of:
  1. RR
  2. 2RW
  3. WW

(See attached Punnett Square foe better visualization)

This means that:

  • 50% the genotype of the resulting flower will be RW (Pink),
  • 25% the genotype of the resulting flower will be RR (Red).
  • 25% the genotype of the resulting flower will be WW (White).

For Problem 2:

The genotype of the resulting flower crossing one red four o' clock flower and one pink four o' clock flower are as follows:

  • The genotype of the RED four o'clock flowers is RR.
  • The genotype of the PINK four o'clock flowers is RW.
  • Crossing RR x RW will result to a genotype of:
  1. 2 RR
  2. 2 RW

(See attached Punnett Square foe better visualization)

This means that:

  • 50% the genotype of the resulting flower will be RW (Pink),
  • 50% the genotype of the resulting flower will be RR (Red).
