ANSWER
Strong smelling (SS) flower = 407
Weak smelling (ss) flower = 17
Intermediate smelling (Ss) flower= 170
The population of wildflower is in Hardy- Weinberg equilibrium
Frequency of S and s alleles-
The formula for this is
F(S)= (2nSS+ nSs) / 2N
F(s) = (2nss+ nSs) / 2N
Frequency of S
= (2X407 + 170 )/ 2X594
=(814+170)/ 1188
=984/1188
=0.83
Frequency of s
= (2X17 + 170 )/ 2X594
= (204 ) / 1188
=0.17
S+s=1
0.83 + 0.17 =1
So the population is in Hardy-Weinberg equlibrium.
The frequency of S is 0.83 and s is 0.17.
Hardy-Weinberg equilibrium-
- Large population size
- Random mating
- No migration in or out
- No natural selection
- No mutation.
GOOD LUCK.

You are doing and experiment on inbreeding in Phlox plants with a single-locus polymorphism in flower color. WW genotypes have white flowers, PP genotypes have purple flowers, and WP genotypes have magenta flowers. You construct an artificial population in the greenhouse consisting of 50 white-flowered phenotypes and 50 purple-flowered phenotypes. You then cross all individuals randomly and grow out 100 F1 seeds. What are the genotype frequencies among the F1 offspring if you assume Hardy Weinberg equilibrium?

1. You are studying a population of sandblossoms (Linanthus parryae) that has individuals with blue and white flowers. The allele for white flowers (A) is dominant to the allele for blue flowers (a). In the population you survey, 91 out of 100 individuals have white flowers. Based on this information: a. Calculate the frequency of the A and a alleles. b. Calculate the numbers of each genotype. 2. A population of snapdragons (Antirrhinum hispanicum) has two additive alleles for flower...

In recent years, some leopard populations have suffered from a loss of habitat. You are part of a research team that is studying the effects that decreased range has on these populations. Your team observed that a portion of one population relocated to the desert and merged with another small leopard population after its own habitat was threatened by deforestation. You have been assigned to lead the study of this new population and look at its gene pool make-up. In...

You have a population with three alleles: G_1, has a frequency of 0.1, G_2 has a frequency of 0.7, and G_3 has a frequency of 0.2. What are the possible genotypes in this population, and what frequency do you expect for each genotype in the next generation if the population is in Hardy-Weinberg Equilibrium? What data would you need to collect about this population and how would you use this data in order to determine whether or not the population...

Assume you have a population of stinkbug larvae scored for their genotypes at the PGI-2 allozyme locus: PGI-2a/PGI-2a: 125 individuals PGI-2a/PGI-2b: 250 individuals PGI-2b/PGI-2b: 125 individuals Now assume that only 70% of the heterozygotes survive to adulthood and become stinkbugs. a) Calculate the observed genotype and allele frequencies for the initial larvae. b) Calculate the expected Hardy-Weinberg genotypic frequencies for the larvae. Are the larvae in Hardy-Weinberg equilibrium? c) What are the genotypic and allele frequencies among adults in the...

2. Alleles D and L are codominant alleles that define fur color in Madagascar lemurs. Lemurs that are homozygous for allele D (genotype DD) have dark brown fur. Lemurs that are homozygous for the L allele (genotype LL) have very light brown fur. The DL heterozygotes are generally light brown, but they have a dark patch or a collar around their neck. Among the 600 Lemurs that you studied on Madagascar, the distribution of genotypes was as follows: Dark brown...

The occurrence of the NN blood group genotype in the US population is 1 in 400, consider NN as the homozygous recessive genotype in this population. You sample 1,000 individuals from a large population for the MN blood group, which can easily be measured since co-dominance is involved (i.e., you can detect the heterozygotes). They are typed accordingly: BLOOD TYPE GENOTYPE NUMBER OF INDIVIDUALS RESULTING FREQUENCY M MM 490 0.49 MN MN 420 0.42 N NN 90 0.09 Using the...
