You are doing a project on microevolution in a plant population. You observe a population of 100 plants, 25 red, 45 pink and 30 white. You return the next spring to find that the population is now made of 200 plants composed of 50 red, 90 pink, and 60 white flowers. Which conclusion would be most accurate?

A. This population is not evolving because there are too few offspring in the 2nd generation.

B. This population is evolving because there are more of each plant one year later.

.C. This population is not evolving because the frequency of the B and b alleles is the same in the two populations.

Answer #1

Solution - Option C

This population is not evolving because the frequency of the B and b alleles is the same in the two populations.

25 red, 45 pink and 30 white became 50 red, 90 pink, and 60 white. ie Only the total number changed, (from 100 to 200) there is no change in the allele frequency. This means that the population is in Hardy-Weinberg equilibrium and alleleic frequencies remains the same for both the generations. Therefore option A and B are wrong

You are studying a population of snapdragon plants on Membata Island. In snapdragons, the dominant allele CR encodes red flowers and the recessive allele CW encodes white flowers. Plants with a heterozygous CRCWgenotype have pink flowers. You have counted 10,000 snapdragon plants on Membata Island. You have recorded that 9025 plants have red flowers, 950 plants have pink flowers, and 25 plants have white flowers. If this population is at a Hardy-Weinberg equilibrium, what are the values of p and...

Suppose you have a plant with petals that are normally blue. Suddenly you see some white-petaled plants. Cross 1: You cross the white with the blue and you get all an F1 population that is all blue. In the F2 generation you see a ratio of 101:33 blue to white-petaled plants. Another line of flowers shows pink petals. Cross 2: You cross the pink with the blue and once again the F1 generation shows all plants with blue petals. However,...

In snapdragons, the plant height gene and the flower color genes are located on different chromosomes. Tall (T) is dominant to dwarf (t). Red flowers (FR) are incompletely dominant to white (FW), with the hybrid being pink. A homozygous tall-white is crossed to a homozygous dwarf-red,. The F1 plants are then self-fertilized to produce an F2 generation. a. What is the genotype and phenotype of the F1? b. What proportion of the F2 will have pink flowers? c. What proportion...

In a natural population of 1892 monkeyflower plants at Lake Tahoe, you notice that there are three flower colors: red, pink, and orange. You breed the plants in the lab, and show that flower color is controlled by a single gene (FC) with two alleles, FC1 and FC2. FC1/FC1 homozygotes produce red flowers, FC1/FC2 heterozygotes produce pink flowers, and FC2/ FC2 homozygotes produce orange flowers. You go back to your study site at Lake Tahoe and notice that both bumblebees...

You are studying inheritance of various characters in marigolds including flower color (purple or blue), seed color (white or brown) and seed shape (round or oblong). When you cross a plant that is true breeding for blue flowers, white and oblong seeds with a plant that is true breeding for purple flowers, brown and round seeds you find that all of the offspring have blue flowers, and round, white seeds. You then cross these F1 plants with each other and...

You are studying hair color in a population of cattle.  You have determined that cattle that are homozygous for one allele (the “red” allele) have red hair and cattle that are heterozygous (for the “red” allele and the “white” allele) have a mix of red and white hair.  You never observe live cattle that are homozygous for the white allele and have determined that cattle with this genotype have white hair but do not survive and are always stillborn.  In your population, 75%...

1. a.) Suppose that you have a batch of red- and white-flowering pea plants. The red-flowering plants are of genotype CC or Cc and the white-flowering pea plants are of genotype cc. All three genotypes CC, Cc, and cc are equally represented in the batch. You pick one plant at random and cross it with a white-flowering pea plant. What is the probability that the offspring will have red flowers? b.) A drug company claims that a new headache drug...

A population of plants displaying incomplete dominance for flower color (determined by one gene with only two alleles) has 60 individuals with red flowers (RR), 20 individuals with pink flowers (Rr), and 20 plants with white flowers (rr). What would you expect the phenotypic ratios to be in the future assuming the population is allowed to move to Hardy-Weinberg equilibrium? (show your work). The population of deer is currently 2,000 individuals. The population can be described by a logistic model...
