Conservation biologists working with the Florida panther have set out camera traps to estimate the overall population.

Help the biologists determine the best conservation action in order to protect and boost the genetic health of the remaining population.   The current population of Florida panthers in this example is twenty which is based upon available habitat.  Eighteen of the panthers are heterozygous [Aa].  Scientists have determined that eighteen is the minimum viable population for the Florida panthers.   If eighteen of the panthers are heterozygous and if homozygous recessive individuals die before reproducing, what is the genotype for the remaining two panthers?     Using the Hardy – Weinberg equations, determine the frequencies of the dominant and recessive alleles.     This population of panthers reproduces and the resulting population is also twenty individuals. Based on the allele frequencies calculated in part b, calculate the genotypic frequencies for the homozygous dominant genotype, heterozygous genotype, and homozygous recessive genotype.     How many of the twenty panthers in this generation will suffer from the disease and die?     What is the number of survivable Florida panthers?

Question

Conservation biologists working with the Florida panther have set out camera traps to estimate the overall population. Through a combination of live trapping and hair snares, the biologists have worked out the exact genetics for two alleles in all remaining individuals. The homozygous recessive state causes a debilitating disease and the panthers die before reproducing. Biologists have found a high incidence of heterozygous individuals. Help the biologists determine the best conservation action in order to protect and boost the genetic health of the remaining population.   The current population of Florida panthers in this example is twenty which is based upon available habitat.  Eighteen of the panthers are heterozygous [Aa].  Scientists have determined that eighteen is the minimum viable population for the Florida panthers.

 

  1. If eighteen of the panthers are heterozygous and if homozygous recessive individuals die before reproducing, what is the genotype for the remaining two panthers?

 

 

  1. Using the Hardy – Weinberg equations, determine the frequencies of the dominant and recessive alleles.

 

 

  1. This population of panthers reproduces and the resulting population is also twenty individuals. Based on the allele frequencies calculated in part b, calculate the genotypic frequencies for the homozygous dominant genotype, heterozygous genotype, and homozygous recessive genotype.
