The gametes derived from the genotype GGBB include dominant and recessive plus mixed. These could show as GG, BB, GB, and BG although there are some multiples of each.
For a plant with green seeds, the possible genotypes depend on whether green seed color is dominant or recessive. If green is dominant (G), the genotypes could be homozygous dominant (GG) or heterozygous (Gg). If green is recessive (g), the only genotype would be homozygous recessive (gg). Therefore, the possible genotypes for green seeds are GG or Gg, assuming green is dominant.
Using a punnett square - you write the possible gamete combinations of one parent across the top and those of the other down the side.By filling in the square, you determine all the possible allele combinations of the offspring.XRDRdrDrdRDRRDDRRDdRrDDRrDdRdRRDdRRddRrDdRrddrDRrDDRrDdrrDDrrDdrdRrDdRrddrrDdrrdd
The possible gametes produced by an individual with the genotype Ww will be W and w.
A cross between two gg plants, both homozygous recessive, will only produce offspring that are also gg. Since both parents contribute the same recessive allele (g), all the resulting offspring will be gg as well, resulting in 100% of the offspring exhibiting the same traits associated with the recessive genotype.
Eight different gametes can be produced from an individual with genotype Gg RR Tt. This is because of independent assortment of alleles during meiosis which allows for different combinations of alleles to be present in the gametes.

The possible genotypes of gametes are determined by the genetic makeup of an individual and can include combinations of dominant and recessive alleles.
A gamete is haploid (1N) so 'Aa' & 'AA' are diploid and during cell division (mitosis) gametes are formed and then 2 gametes merge together to make a diploid (think of sperm and egg, each is haploid or 1N, when fertilization occurs the egg and sperm form 1 cell that is 2N or diploid). So the possible gametes for 'Aa' would be 'A' & 'a' while for 'AA' the only gametes possible are 'A' If the question is asking what the possible gametes are for 'AaBB' the haploid (gamete) can be 'AB' or 'aB'
i dont nkonw - - - - Ignore that person. If you are using a Punnett Square (2X2 box) then you will see that if you have a Gg (across the top) and gg (down the side) you will have Gg, Gg, gg, gg. The lowercase letters represent recessive traits and the uppercase dominant. The ratios are split into Phenotypes and Genotypes. If you have at least one dominant trait then it is considered a genotype (for this problem Gg GG). Double recessive is a phenotype (double lower case-in this case gg.) Your ratio for the above Gg, Gg, gg, gg is 2:4 (1:2) for both Phenotype and Genotype. Hope this helps!

Yes. Remember that a heterozygote can produce two types of gametes. In this case, the unknown would produce gametes with the dominant allele A or the recessive allele a. The homozygous recessive would still only produce one kind gamete, with the recessive a allele. Therefore, we expect to see only two genotypes in the F1, Aa and aa, in equal proportions.
