A long neck yellow giraffe (T t Y y) mates with a short neck orange giraffe (t t y y). Possible phenotypes: Long/Yellow, Long Orange, Short/Yellow, Short/Orange.
Understand the Problem
The question is asking us to determine the possible phenotypes resulting from the mating of two giraffes with specified genotypes. We will set up a Punnett square to analyze the combination of alleles and identify the resulting phenotypes.
Answer
Long/Yellow 1: Long/Orange 1: Short/Yellow 1: Short/Orange 1.
The possible phenotype ratios are: Long/Yellow 1: Long/Orange 1: Short/Yellow 1: Short/Orange 1.
Answer for screen readers
The possible phenotype ratios are: Long/Yellow 1: Long/Orange 1: Short/Yellow 1: Short/Orange 1.
More Information
The phenotypic ratio is determined by performing a dihybrid cross. Each parent contributes one allele per gene for each trait, resulting in these phenotypes.
Tips
A common mistake is to forget that each parent can contribute different combinations of alleles, so all potential combinations must be considered.
