Answer #1

Example 4:

Answer:

F1 parents : DdRr X DdRr

Punnett square of the cross. The genotypes of the parents in the spaces provided in the punnett square are in Bold.

	DR	Dr	dR	dr
DR	DDRR	DDRr	DdRR	DdRr
Dr	DDRr	DDrr	DdRr	Ddrr
dR	DdRR	DdRr	ddRR	ddRr
dr	DdRr	Ddrr	ddRr	ddrr

Question 21:

Answer:

The possible phenotypes of the F2 population are

Phenotype 1: DDRR, DDRr, DdRR, DdRr

Phenotype 2 : DDrr and Ddrr

Phenotype 3: ddRR and ddRr

Phenotype 4: ddrr

The possible genotype of the F2 population are: DDRR, DDRr, DdRR, DdRr, DDrr, Ddrr, ddRR, ddRr and ddrr.

Base on the results of the punnett square, Genotypic and phenotypic ration of F2 geeration can be calculated.

The phenotypic artion of F2 population are : 9:3:3:1

The genotypic ration of F2 population is : 1:2:1:2:4:2:1:2:1.

Punnett Square for Question #4 is a the top Punnett Square Genotypic ratio: Phenotypic ratio: 5. Purple flowers (P) are completely dominant over white flowers (p). If a pea plant is heterozygous for purple flowers, can any of this plant's offspring have all purple flowers? Think about the different genotypes with which you can cross the hetero- zygous parent: homozygous dominant, heterozygous, and homozygous recessive. Use three Punnett squares to show your work for each possible phenotype. Heterozygous purple pea...
