Question

in a group of cockatiels, some individuals have bright orange cheeks and others have pale orange cheeks. in this group, the gene for the cheek color trait has two alleles. the allele r is for bright orange cheeks, and the allele r is for pale orange cheeks. tiki is a cockatiel from this group. tikis phenotype for the cheek color trait is bright orange cheeks. tikis genotype for the cheek color gene is rr. based on this information, complete the following statement. tiki is ______ for the cheek color gene. heterozygous homozygous

Explanation:

In genetics, a heterozygous genotype has two different alleles for a gene. Here, Tiki's genotype is \(Rr\) (two different alleles \(R\) and \(r\)). A homozygous genotype would have two of the same alleles (e.g., \(RR\) or \(rr\)).

Answer:

heterozygous
