The gene pool.
all of the alleles in a population are it's gene pool
Mendel crossed the dominant purple colour flowered plant with the recessive white colour flowered plant. The F 1 generation produced the heterozygous purple colour flowered (Pp) plants. When two heterozygous pea plants (Pp) are crossed in the F2 generation represented by Pp x Pp, the gametes formed are P and p. Out of the offspring produced, 3 are purple colour flowered plants and 1 is white colour flowered plant. Thus the phenotypic ratio is 3: 1 with one out of four plants being white colour flowered pea plant. When expressed in percentage it is 25%.
There are choices for this question namely:
a. Oil and water
b. Salt and water
c. Brass (and alloy of copper and zinc)
d. Granite (a type of rock with multicolor spots)
The correct answers are
oil and water, and
granite. Heterogenous mixtures are mixtures wherein the solutes can still be identified from each other. Homogenous mixtures are mixtures wherein solutes are completely mixed and cannot be identified. In oil and water, one can identify which is the oil and which is the water. In granite, it is a mixture of different rocks and these different materials can be identified due to the presence of multicolored spots.
