Question

The flowers in a garden at a resort need to be replaced. The choices for the flowers are geraniums (G), impatiens (). petunias (P), and zinnias (2). The head gardener holds an election in which all employees get to vote The results of the election are given in the preference table to the right.

Number of votes 11 14 6 7 6
First Z G G I P
Second G I P P Z
Third P P I Z G
Fourth I Z Z G I

Determine which flowers are selected using the Borda count method.

A. Geraniums
B. Zinnias
C. Impatiens
D. Petunias
E. There is a tie between impatiens and petunias.

Answer 1

When two violet petunias, which are heterozygous (Pp), are crossed, the most probable results of the cross would be 25% red petunias (pp), 50% violet heterozygous petunias (Pp), and 25% violet homozygous petunias (PP). Violet is the dominant trait.

Step-by-step explanation:

When a blue petunia is crossed with a red petunia, all the resulting flowers are violet. This suggests that the blue and red flower colors are both recessive traits while the violet color is a dominant trait. Crossing two violet petunias will likely result in a combination of violet and possibly red or blue flowers if the violet petunias are not true-breeding, indicating incomplete dominance or a recessive allele present in both parents.

Using the information provided that a violet flower crossed with a red flower results in about half violet and half red flowers, the violet color can be characterized as a dominant trait, carrying the dominant allele (P), and the red color as a recessive trait, carrying the recessive allele (p). Therefore, if two violet petunias (Pp) are crossed, the probable result of the cross would be:

• 25% red (pp)
• 50% violet (Pp)
• 25% violet (PP)

Given that violet is dominant, only a petunia inheriting two recessive alleles would display the red color.
