Red-green color blindness is an X-linked recessive disorder that is passed through generations and can be traced by using a pedi
Nostrana [21]

Answer:

Lisa and Monica

Explanation:

<em>The correct answer would be Lisa and Monica.</em>

<u>For X-linked recessive disorders, a female can be unaffected, a carrier, or affected. However, a male can either be affected or unaffected and never a carrier. This is because females have two X chromosomes while males have only one.</u>

In addition, completely filled-in shapes in a pedigree mean that such individuals are affected for the trait in question while half-filled shapes mean the individuals are carriers for the trait.

Hence, individuals in the pedigree that are labeled carriers for red-green color blindness are Lisa and Monica (they both have half-filled shapes).

Readme [11.4K]

Answer:

Signal transduction pathways

Explanation:

Plant hormones act by directly affecting the activities of signal transduction pathways.

Signal transduction pathways are involved in the transfer of signals from outside of the cell to the inside of the cell for the regulation of various cellular activities. For this, the extracellular signalling molecules bind to the receptors that are located on the cell membrane. After their binding due to some change in the receptor molecule, a signal is triggered in to the cell and thus information from outside of the cell is transferred to the inside of the cell through these transduction pathways.

Plant hormones affect these pathways and as a result membranes, enzymes, and genes are also influenced by the plant hormones.
