Purple white and lavendar four oclock flowers why did the four o'clock flower plant give three phenotypes instead 2 is  a genotype that is 2:2 Rr and rr.

The 4'o clock plant, phenotypes , exhibits partial dominance in flower colour, which is why the F1 plant produced by crossing a pure Red flowered plant (RR) with a pure White flowered plant (rr) has pink flowers (Rr).When an F1 plant (Rr) crosses with a pure white flowering plant (rr), the resulting plant will have a genotype that is 2:2 Rr and rr.

The phenotypic, however, will be 2 pink and 2 white at a ratio of 2:2.

The offspring's phenotypic ratio will be 2:2.

Rr × rr

If an ovum is not fertilized _____ production decreases and the ____ is shed
lubasha [3.4K]
If an ovum is not fertilized ESTROGEN production decreases and the LINING OF THE WOMB is shed. As a woman of child bearing age is approaching ovulation, the body increases the production of estrogen hormone, which causes the lining of the uterus to thicken and which also provide a sperm-friendly environment. If fertilization do not take place the body reduces the production of estrogen and the thickened uterus lining will be shed.

During labor, certain hormones are released that cause the contraction of the uterus in order to push the baby out. When those h
DerKrebs [107]

Answer:

The endocrine system assists in maintaining and regulating different functions of the body by producing and discharging hormones. It comprises glands situated throughout the body, which produce chemicals known as hormones directly into the blood. The levels of hormones in the blood are monitored by a highly unique homeostatic mechanism known as feedback.  

The two kinds of feedback are common, that is, negative and positive feedback, of this positive feedback, is the rare mechanism. It augments the changes done rather than opposing them. For example, the discharging of oxytocin from the posterior pituitary gland at the time of labor is an illustration of a positive feedback mechanism.  

The stimulation of the muscle contractions, which pushes the baby via the birth canal is done by oxytocin. This discharging of oxytocin leads to an augmented or stronger contraction at the time of labor. This contraction is enhanced and intensify until the baby comes out of the birth canal. However, when the stimulus to the pressure receptor terminates, the generation of oxytocin ceases, which eventually results in the stopping of labor contractions.
