Concept explainers
a.
To define:
At the hair length and furnishings genes, what is the correct genotype of the long-haired dog without furnishings?
Concept introduction:
Genes influence the physical, behavioral, and biochemical traits of all organisms. Genes transfer genetic information from one generation to another. Alleles are different versions of a gene. If the genotype contains two different alleles of a gene, it is known as heterozygous for that particular gene. If the genotype contains two copies of the same allele (two similar alleles of a gene), it is known as homozygous for that particular gene.

At the hair length and furnishings genes, what are all the possible genotypes of the short-haired dog with furnishings?
