Question 14 

#3.The change in population size for Canada in 2015 was an increase of 272 990. In the same year, the number of births was 392 902, the number of deaths was 269 012, and the immigration number was 271 660.

What was the number of people who emigrated from Canada in 2015?

Select one:
a. 147 770
b. 125 220
c. 217 264
d. 122 560
given: # of births=39902
# of deaths=269012
#i=271660
formula is  ∆N = (birth + immigration) - (mortality + emigration).
what they are looking for # of emigration. I got d as an answer is this correct? please let me know soon, thank you so mcuh. And have a great evening Wink Face

Question 15 

1) A rabbit warren has 300 individuals. The coat colour of rabbits is expressed through incomplete dominance. The coat colour can be dark brown, light brown, or white.

There are 81 dark brown rabbits, 150 light brown rabbits, and 69 white rabbits. Assume that all of the conditions are met for a population in Hardy–Weinberg equilibrium.

What is the genotype frequency of light brown rabbits, the phenotype frequency of white rabbits, and the dark brown allele frequency?

a. Genotype of Light Brown Rabbits        Phenotype of White Rabbits     Dark Brown Allele Frequency
                           0.50                                                           0.23                                                    0.52


b. Genotype of Light Brown Rabbits          Phenotype of White Rabbits    Dark Brown Allele Frequency
                            0.27                                                            0.48                                                    0.52


c. Genotype of Light Brown Rabbits          Phenotype of White Rabbits     Dark Brown Allele Frequency
                             0.27                                                           0.23                                                       0.77


d. Genotype of Light Brown Rabbits          Phenotype of White Rabbits    Dark Brown Allele Frequency
                            0.50                                                          0.48                                                       0.77











2) In mice, albinism (g) is recessive to grey coat colour (G). The fur colour in mice is a single gene trait controlled by two alleles.

In an ideal mouse population exhibiting Hardy–Weinberg equilibrium, a grey mouse mated with an albino mouse. Over the course of several months, 64 pups were born.

If the albino allele has a frequency of 0.375, which of the following rows identifies the number of the grey and albino alleles in the population of 64 pups?

a. Grey Allele      Albino Allele
       80                         48


b. Grey Allele         Albino Allele
          48                        80

c. Grey Allele          Albino Allele
           40                        24

d. Grey Allele          Albino Allele
        24                             40










3) Grey eyes (b) are recessive to brown eyes (B) in rabbits. In an ideal rabbit population exhibiting Hardy–Weinberg equilibrium, if allele b has a frequency of 0.48, what percentage of the population is heterozygous for this trait?

Round your answer to the nearest whole number.
