Flower color in snapdragons is due to a gene with incomplete dominance: CRCR plants have red flowers, CRCW have pink flowers, an
VLD [36.1K]

Answer:

CRCR × CWCW

Explanation:

Flower color in snapdragons exhibits incomplete dominance wherein the heterozygous genotype exhibits the blend phenotype. To have all the pink-flowered progeny, all the progeny should have CRCW genotype and must obtain CR allele from one parent and CW from the other.

Among the given options, parent genotype "CRCR × CWCW" will give all the pink-flowered progeny. The parent plant with genotype CRCR would produce all the gametes with "CR" alleles while the parent with genotype "CWCW" would produce all the gametes with the "CW" allele. The random fusion of these gametes from the two parents would give all pink-flowered progeny with genotype "CRCW".

Classify each item as being associated with light positioning (controlling how and where light strikes the retina) or sensory pr
Brilliant_brown [7]

Answer:

- light positioning: c. Extrinsic muscles; d. Pupil

- sensory processing: a. Photoreceptors; b. Occipital cortex; e. Bipolar cells

Explanation:

Extrinsic (extraocular) muscles are muscles that modulate both eye movement and position, whereas intrinsic (intraocular) muscles are muscles that focus the eye and control how much light enters into the eye. The pupil is the black center of the eye within the iris through which light passes before being focused onto the retina. Photoreceptors are specialized neurons located in the retina that respond to light, converting it into electrical signals that can stimulate biological processes. Photoreceptors in the retina are divided into two categories 1-rods (responsible for vision at low light levels), and 2-cones (active at higher light). Bipolar cells are neurons that transmit signals from the photoreceptors to the ganglion cells, thereby processing light signals received from rods and cones. The occipital cortex is a brain region that represents the visual processing center and contains most of the anatomical region of the visual cortex.
