The appropriate answer is D ! in this the dominant allele is not fully dominant ! this is seen in Snapdragon !
so answer is D
Answer:
Option (A), (C) and (D).
Explanation:
The concept of law of dominance was explained by Mendel while working on the pea plant <em>Pisum sativum. </em>According to this law, the trait which is able to express itself even in hetrozygous condition, the trait is called dominant trait. The trait that are unable to express itself, the trait is called recessive trait.
Here, T means tall and t is short. T shows the dominant trait whereas t is recessive trait. T trait can express itself in heterozygous condition as well. So, TT, Tt and TTTT shows the tall individuals and tt is short individual.
Thus, the correct answer is option (A), (C) and (D).
The hormone ADH operates by negative feedback mechanism in that when the body's tissues lack water, it causes the nephrons to retain water to prevent the body's tissues drying out.
Answer:
In human vision, the cone visual opsins are grouped into four photoreceptor protein families LWS, SWS1, SWS2, RH2
.
- SWS1: produce pigments sensitive to very short wavelengths, UV-violet, 360-450 nm.
- SWS2: produce pigments sensitive to short wavelengths, blue, 450-495 nm
- RH2: produce pigments sensitive to medium wavelengths, green, 495-560 nm
- LWS: produce pigments sensitive to long wavelengths, yellow-red, 560-770nm.
Explanation:
Photoreceptor proteins are light-sensitive proteins that mediate light-induced signal transduction, thus they are involved in the sensing and response to light in a variety of organisms.
The photoreceptor proteins are classified based on the chemical structure of the chromophores involved, the light absorption and on the protein sequence.
This photoreceptor proteins are located at the cone photoreceptor cells and are responsible of photopic vision.
For scotopic vision, rhodopsin is responsible. Rhodopsins are the visual pigments (visual purple) of the rod photoreceptor cell in the retina. They are responsible of human vision in dim light, as it contains a sensory protein that converts light into an electric signal.
