Draw a table that is 2x2. On the top, write a capital R over on box and a lowercase r over the second. On the side, write a lowercase r next to one box and another lowercase r by the other. The top left box would have Rr. The top right would have rr. The bottom left would have Rr and the bottom right would have rr. The probability would be 50%. There is a 50% chance of having wrinkled seeds
Fossils give evidence upon organisms the past are not the same as those found and demonstrate a progression of evolution.
Nephron helps the urinary system to rid off metabolic waste in our system.
As we can see in the pedigree, both of the parents do not possess the trait, but one of the four offspring (marked with red) is expressing the trait.

They lack colors such as blue and red. any primary color.
