Question

f). the allele for straight fur (f) is dominant to the allele for wavy fur (f). the punnett square below models the results of a cross between two hamsters. both hamsters are heterozygous for the coat texture gene (ff). what is the expected ratio of offspring with wavy fur to offspring with straight fur? choose 1 answer: a 1 : 3 b 1 : 1 c 3 : 1

Explanation:

Step1: Identify genotypes for wavy and straight fur

Wavy fur is recessive, so only \( ff \) shows wavy fur. Straight fur is dominant, so \( FF \) and \( Ff \) show straight fur.
From the Punnett square: \( ff \) (wavy) count = 1; \( FF, Ff, Ff \) (straight) count = 3.

Step2: Calculate the ratio

Ratio of wavy (\( ff \)) to straight (\( FF + Ff + Ff \)) is \( 1:3 \).

Answer:

A. \( 1 : 3 \)
