Final answer:
The statement that one allele for fur color and one for fur length is passed to offspring from each parent is true, reflecting principles of Mendelian genetics and the inheritance of traits.
Step-by-step explanation:
The statement "One allele for fur color and one allele for fur length is passed to offspring from each parent" is true. In genetics, this concept is central to the inheritance of traits and is addressed by Mendelian principles of inheritance. Each parent contributes one allele for each characteristic to their offspring. This is seen in a monohybrid cross, where organisms that are heterozygous (hybrids) for a trait carry one dominant and one recessive allele. Similarly, in organisms with multiple alleles for a particular gene, such as the rabbit coat color (C) gene, a specific hierarchy of dominance can exist. Dominance and epistasis, where one gene can influence the expression of another (such as in the pigment production in mice, where the C gene is epistatic to the A gene), are also important in determining the phenotype of the offspring.
