(eg. Aa Bb Cc)
First would be to find out all the different combinations of these traits
ABC ABc AbC Abc aBC aBc abC abc
Then would be to make a "cross" out of them
ABC ABc AbC Abc aBC aBc abC abc
ABC
ABc
AbC
Abc
aBC
aBc
abC
abc
Then would be to 'fill in' the cross by adding them up
ABC ABc AbC Abc aBC aBc abC abc
ABC AABBCC AABBCc AABbCC AABbCc AaBBCC AaBBCc AaBbCC....
ABc
AbC
Abc
aBC
aBc
abC
abc
Hope the rest you can figure out,
Sincerely,

A dihybrid cross is a cross between a P generation that differs in two traits rather than one. For example, a pea plant that is homozygous for the dominant green pod color (GG), and dominant tall height (TT) crossed with a pea plant that is homozygous for the recessive yellow pod color (gg) and recessive short height (tt) will produce hybrid offspring that are heterozygous for pod color and height (GgTt), and will have green pod color and tall height. GGTT x ggtt --> GgTt
The process you are referring to is called cross-pollination. It occurs when pollen from the flower of one plant is transferred to the stigma of a flower on a different plant of the same species. This process helps in genetic diversity and the production of seeds for the continuation of the plant species.
Yes, water can cross the lipid bilayer through a process called simple diffusion.
cross fertilization
Yes, small polar molecules can cross the cell membrane through a process called passive diffusion.
64
In a trihybrid cross, which involves three traits, each parent forms 8 different gametes due to independent assortment of alleles during meiosis. Therefore, in the F1 generation of a trihybrid cross, 64 different genotypic combinations are possible (8 x 8).
100%
It does.. But you knew anything you would try to answer it 👏
In a trihybrid cross, a segregation ratio of 27:9:9:9:3:3:3:1 (9:3:3:1 ratio raised to the third power) is expected. This ratio represents the distribution of different combinations of alleles from the three genes being studied.
In a trihybrid cross, the offspring would inherit one allele from each parent for each of the three traits (Tall, green, and round). Since the parents are homozygous for all traits (ttggrr x ttggrr), all the offspring would be tall, green, and round, resulting in 100% of the offspring being tall, green, and round.
No. it is not permissible!
