Generally, you can calculate it with this formula: df = (r-1)(c-1) where r is the number of rows and c is the number of columns.
Answer:
50% probability of Pp (purple) or pp (white) genotype.
Explanation:
P = purple gene
p = white gene
Punnet squares show the possible genotypes and probabilities of each genotype in the offspring of a cross:
Purple flower genotype (heterozygous) = Pp
White flower genotype = pp
Punnet Square:
![\left[\begin{array}{ccc}&P&p\\p&Pp&pp\\p&Pp&pp\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%26P%26p%5C%5Cp%26Pp%26pp%5C%5Cp%26Pp%26pp%5Cend%7Barray%7D%5Cright%5D)
Potential genotypes for offspring are Pp and pp;
According to the Punnett square, 2 of 4 offspring will have the Pp genotype and the other 2 will have pp genotypes;
This means 2 should be purple and 2 white;
Or, there is a 50% chance of having either genotype, of being purple or white.
<span>Answer: Bone marrow stem cells have been shown to generate cartilage, bone, and muscle when injected directly into the injured site
Stem cells could differentiate into the various type of cells, makes them able to regenerate part of the body that doesn't have regeneration abilities. The cell that involved the </span><span>tear of the rotator cuff would be cartilage, bone, and muscle. Stem cells could replace the damaged cells so that the muscle and joint might work better. </span>
Moonlight is no longer thought of as the cause. In the 16th century, moonmilk, a soft white limestone precipitate found in caves, was thought to be caused by the rays of the Moon.
