Answer: The expected phenotype ratio of cross between CR and Cp is 1:1:2.
1 for CC,
1 for Cp, purple
2 for CR and Rp(red) all which are offsprings from the cross.
For cross between Cp and Cw, phenotype ratio is 1:1:2.
1 for CC,
1 for Cw, white,
2 for Cp and pw,purple.
Explanation:
Phenotype gives the observable characters of an individual.
Here, the character observed is flower color of tulip species.
The expected phenotype ratio of cross between CR and Cp is 1:1:2. The offsprings from the cross are CC, Cp,CR and Rp
1 for CC,
1 for Cp, purple
2 for CR and Rp red, since red is dominant over purple.
For cross between Cp and Cw, phenotype ratio is 1:1:2. The offsprings from the cross give CC, Cw, Cp and pw
1 for CC,
1 for Cw, white,
2 for Cp and pw,purple since purple is dominant over white.
