Answer the following question given this paragraph: A sex-linked trait is a trait whose allele is found on a sex chromosome. The human X chromosome is significantly larger than the Y chromosome; there are many more genes located on the X chromosome than there are on the Y chromosome. As a result there are many more X-linked traits than there are Y-linked traits. Most sex-linked traits are recessive. Because males carry only one X chromosome, if they inherit a recessive sex-linked gene they will show a sex-linked condition; there is no dominant allele to offset the recessive allele. Q: What is a trait whose allele is found on a sex chromosome called? Choices: - dimorphism - linked trait - gender trait - genomic trait - sex-linked trait A:
**Answer**
sex-linked trait

*Question*
Answer the following question given this paragraph: Short and Long Reflexes Somatic reflexes involve sensory neurons that connect sensory receptors to the CNS and motor neurons that project back out to the skeletal muscles. Visceral reflexes that involve the thoracolumbar or craniosacral systems share similar connections. However, there are reflexes that do not need to involve any CNS components. A long reflex has afferent branches that enter the spinal cord or brain and involve the efferent branches, as previously explained. A short reflex is completely peripheral and only involves the local integration of sensory input with motor output (Figure 15.8). Q: A short reflex is completely what and only involves the local integration of sensory input with motor output? Choices: - neuronal - physiological - central - peripheral A:
**Answer**
peripheral
