-Dominant- [34]

Answer:

a) R= allele for red colored flower

I= Allele for ivory flowers

b) Genotype of pink flowered plant: RI

c) Incomplete dominance

d) 100%

Explanation:

When the dominant allele is not able to fully mask the expression of the recessive allele in the heterozygous state, it is said to be incomplete dominance. The R and I alleles impart red and ivory color respectively to the flowers of the snapdragon plant. The heterozygous genotype "RI" imparts a pink color to the flowers and therefore, the alleles are said to exhibit incomplete dominance.

The genotype of red-flowered snapdragon plant = RR. The genotype of ivory flowered snapdragon plant= II. When a red-flowered snapdragon plant is crossed with an ivory flowered snapdragon plant, the progeny is heterozygous in nature with the "RI" genotype. The phenotype of the progeny is "Pink flower" since the R allele is incompletely dominant over the allele I.

iragen [17]

Suppose bad weather and pollution dramatically reduce the supply of crawfish in Louisiana next year. This would most likely lead to an increase in the marginal utility of crawfish consumption.

Marginal utility of a commodity or service is the change in total utility resulting from consuming an extra unit of that commodity or service.

The marginal utility of a good or service tells about the happiness experienced or the contentment obtained by the consumers as a consequence of the increment or decrement in consumption by one unit.

There exist three kinds of marginal utility. They include positive, negative as well as zero marginal utility.
