Resplendent quetzal (Pharomachrus mocinno) is a beautiful bird species that lives in the tropical forests of Central America. Assuming that you started a breeding program and you would like to breed resplendent quetzal to produce longer tails. You measured 50 resplendent quetzals and obtained a mean tail length of 85.4 cm. You selected 10 resplendent quetzals with longest tails as breeders. The mean tail length of the breeders is 91.2 cm. After mating, offspring of the resplendent quetzal breeders have a mean tail length of 87.7 cm. What is the heritability of tail length in this resplendent quetzal population

Answer:

The value is  [tex]H  =0.3966[/tex]

Step-by-step explanation:

From the question we are told that

   The  sample size is  n =  50

  The  mean tail is  [tex]\= x  =  85.4 \cm[/tex]

  The  number  of resplendent quetzals selected as breeders  is  [tex]k =  10[/tex]

   The  mean tail breeders  is  [tex]\= x_1 =  91.2 \ cm[/tex]

   The mean tail of the breeders after mating  [tex]\=  x_2  =  87.7 \ cm[/tex]

   

Generally the selection differential is mathematically represented as

    [tex]D  =  \= x_1 -  \= x [/tex]

=>  [tex]D  = 91.2-  85.4 [/tex]

=>  [tex]D  = 5.8 \  cm [/tex]

Generally the selection response  is mathematically represented as

       [tex]S =  \=  x_2  - \= x[/tex]

=>    [tex]S =  87.7   - 85.4[/tex]

=>    [tex]S =2.3 \  cm [/tex]

Generally the  heritability of tail length in this resplendent quetzal population is mathematically represented as

     [tex]H  =  h^2 =  \frac{S}{D} [/tex]

=>   [tex]H  =  h^2 =  \frac{2.3}{5.8} [/tex]

=>  [tex]H  =  h^2 =  \frac{2.3}{5.8}  [/tex]

=>  [tex]H  =  h^2 = 0.3966/tex]
