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

Although cells are diverse, all cells have certain parts in common. The parts include a plasma membrane, cytoplasm, ribosomes, and DNA. The plasma membrane (also called the cell membrane) is a thin coat of lipids that surrounds a cell.

Answer:
X-linked/Sex-linked recessive inheritance
Explanation:
<em>The most likely mode of inheritance of the trait is an X-linked recessive inheritance.</em>
The sex chromosome of a male is XY while that of a female is XX. The Y chromosome is hypothesized not to carry any allele ordinarily. Hence, a male child only needs to inherit one affected allele to become affected for recessive X-linked traits.
During gamete formation, the sex chromosome of the male segregates into X and Y gametes while that of the female segregates into X and X gametes. During fertilization, the X gamete of the male is usually inherited by the female while one of the X gametes of the female is usually inherited by the male.
<u>Assuming a father is affected for an X-linked recessive trait, the affected X chromosome will be passed to a female child and such a child would be a carrier, rather than being affected since she requires the two X chromosomes to be affected in order to exhibit the trait. </u>
<u>The affected X chromosome is thus passed to her male child according to the law of inheritance of the sex chromosome. Hence, the grandson of the affected man inherits the trait through the daughter of the affected man.</u>
