It is true that a mixed reference "locks" one part of the cell reference while the other part can change. Mixed reference contains both relative and absolute references, where mixed reference locks one part and while the other can change. when one enters a formula into a cell, Excel interprets cell references in the formula in relation to a cell's location. In excel the numbers, text, or cell references used by the functions to return a value.
they are all used as energy for a cell.
Answer:
GgRr
Explanation:
as it was stated in the question that one of the parent is a heterozygote for both alleles, It could only be written as GgRr. A cross between this parent and the double recessive parent would also give rise to the following listed genotypes, assuming the second Gr/gr in the question to be gr/gr. thus, we would have:
GgRr x ggrr
GR Gr gR gr
gr GR/gr Gr/gr gR/gr gr/gr
The toxins would enter through the Xylem.
