Question

In chickens, F is the trait for frizzled feathers and S is the trait for straight feathers. Since both are dominant, when they are inherited together, the result is a "slightly frizzled" chicken. Show Punnett squares for the following crosses:
(a) frizzled x straight feathers
(b) slightly frizzled x slightly frizzled feathers
(c) frizzled x slightly frizzled feathers​

Answer 1

(a) fizzled × straight feathers is the Punnett square shows the result of crossing two chickens with mildly frizzled features.

Explanation:

• In Chicken, F is trait for Frizzled feather. S is the trait for straight feather.

• A model that can be used to represent the Punnett square and model as Polynomial.

• Punnett square is a diagram that is used to predict the outcome of a particular cross experiment.

• It is used to determine the probability of an offspring having a particular genotype.

• The cross of F and S trait we get,

                             $\[\begin{matrix} FF & FS \\ FS & SS \\\end{matrix}\]$

           where FF denoted Bad feathers

           SS denotes smooth feathers

           FS denotes Frizzle

• Hence the Punnett square of the cross is frizzled × straight feathers
