Describe how the relative numbers of PDS and NPDs can be used to establish linkage.
Mandarinka [93]

Answer:

Linkage may be defined as the transmission of chromosome to the next generation that are located on same chromosome. Linkage results in the formation of recombination progeny.

PDS (parental ditypes) and non parental diypes can be used to find linkage in the Neurospora and other organism Parental ditypes has the genotype same as parental genotype whereas non parental ditypes contains recombinant progeny. If the ratio and arrangement of PDS and NPDs is 2:4:2 or 2:2:2:2. This means linkage is present between the gene and centromere of an organism.

Damage to sensory receptor cells would most likely result in ________. I. confusion of visual and auditory input II. inaccurate
MatroZZZ [7]

Answer:

The correct answer is: None of the above. The accurate answer is: Problem or inability in detecting the sensory information.

Explanation:

  • Sensory receptor cells form the part of the sensory epithelial layer that are present in the form of a lining in all sensory organs.
  • These sensory cells possess some specialised receptor molecules, usually on the surface of the cells, that can sense different types of sensory signals like light, in case of eyes, smell is case of nose, taste in case of tongue and sound in case of ears.
  • Any damage caused to these cells will adversely affect their capability to perceive or receive or detect the sensory signals.
  • Option I is incorrect because sensory cells are not only present in the eyes and ears but also in nose, tongue, skin. The activity of the sensory cells of one organ is independent of the activity of sensory cells of other organs hence, damage to the sensory cells of one organ will not create any confusion in different sensory inputs.
  • Option II is incorrect because integration of all the sensory impulses occur in the brain after the impulse has been received and detected by multiple sensory receptor cells and send to the brain through the sensory neurons.
