8. In snapdragons, red flower (R) color is incompletely dominant over white flower (1) color. The heterozygous (Rr) plants have pink flowers.
A. If a red-flowered plant is crossed with a white-flowered plant, what are the genotypes and phenotypes
of the plants F1 generation?
B. What genotypes and phenotypes will be produced in the F2 generation?
C. What kinds of offspring can be produced if a red-flowered plant is crossed with a pink-flowered plant?
D. What kind of offspring is/are produced if a pink-flowered plant is crossed with a white-flowered plant?

A. Genotypes: Rr

Phenotypes: All Pink

B. Genotypes in the F2 generation: RR, 2Rr, rr

Phenotypes: red, pink and white

C. 1RR (red): 1Rr (pink).

D. 1Rr (red) : 1rr (white).

Explanation:

This question involves one gene coding for flower color in snapdragon plants. The allele for red color (R) is incompletely dominant over the allele for white color (W), to form an intermediate pink color (RW).

A. If a red-flowered plant (RR) is crossed with a white-flowered plant (rr), the genotypes of the offsprings will be Rr with a pink color phenotype.

B. In the F2 generation i.e. Rr × Rr, the following will be produced: RR (red), 2Rr (pink), and rr (white).

C. if a red-flowered plant is crossed with a pink-flowered plant, the following will be produced: 1RR (red): 1Rr (pink).

D. if a pink-flowered plant is crossed with a white-flowered plant, the following will be produced: 1Rr (red) : 1rr (white).

explanation:

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
