All Ww offspring refer to the genetic outcome of a cross between two organisms where one is homozygous dominant (WW) and the other is heterozygous (Ww) for a particular trait. In this scenario, the possible genotypes of the offspring would be either WW or Ww. Thus, all offspring would display the dominant trait associated with the W allele, but 50% would be homozygous (WW) and 50% heterozygous (Ww). Therefore, all offspring would express the dominant phenotype, but their genotypes would vary.
If winged dragons are represented by the dominant allele (W) and wingless dragons by the recessive allele (w), a heterozygous dragon would have the genotype Ww. When a wingless dragon (ww) is crossed with a heterozygous dragon (Ww), the possible genotypes of the offspring are WW, Ww, and ww. This results in a 50% chance of offspring being wingless (ww).
To yield only white offspring, both parent organisms must carry the alleles for white coloration. In genetics, if white is a dominant trait, then a combination of two homozygous white parents (WW x WW) or a homozygous white parent (WW) with a heterozygous parent (Ww) will produce only white offspring. If white is a recessive trait, only two homozygous recessive parents (ww x ww) will produce exclusively white offspring.
Usually, the parent flies will have a different genotype to the F1 generation (their offspring). For example, if the parents had WW (black eyes) and ww (white eyes), their offspring would all have Ww (black eyes). If you were experimenting further, you would want the F1 generation to cross - with Ww X Ww. If you did not remove the parental generation, you could have crosses between them and the F1 generation, which would result in different genotypes. If the parents were not removed, you could have the following crosses: Ww X WW Ww X ww WW X ww Ww X Ww The only cross that you would desire in the experiment would be F1 X F1 (Ww X Ww), which would give you the desired genotypes for the F2 generation.
When a heterozygous long-winged fly (LW) is crossed with a short-winged fly (ww), the possible genotypes of the offspring are LW and ww. This results in a 50% chance of producing long-winged offspring (LW) and a 50% chance of producing short-winged offspring (ww). Therefore, there is a 50% likelihood that the offspring will have long wings.
If we cross a homozygous dominant fruit fly with straight wings (WW) and a homozygous recessive fruit fly with curly wings (ww), all offspring in the first generation (F1) will be heterozygous (Ww) and exhibit straight wings. If we then cross two F1 flies (Ww x Ww), the second generation (F2) will show a phenotypic ratio of 3 straight-winged flies to 1 curly-winged fly, resulting in about 75% straight wings and 25% curly wings.
It would look like this. --¦ W W -------------- w¦ Ww Ww w¦ Ww Ww All the offspring would be black-furred, all carrying one dominant gene and one recessive.

If winged dragons are represented by the dominant allele (W) and wingless dragons by the recessive allele (w), a heterozygous dragon would have the genotype Ww. When a wingless dragon (ww) is crossed with a heterozygous dragon (Ww), the possible genotypes of the offspring are WW, Ww, and ww. This results in a 50% chance of offspring being wingless (ww).
To yield only white offspring, both parent organisms must carry the alleles for white coloration. In genetics, if white is a dominant trait, then a combination of two homozygous white parents (WW x WW) or a homozygous white parent (WW) with a heterozygous parent (Ww) will produce only white offspring. If white is a recessive trait, only two homozygous recessive parents (ww x ww) will produce exclusively white offspring.

When a heterozygous long-winged fly (LW) is crossed with a short-winged fly (ww), the possible genotypes of the offspring are LW and ww. This results in a 50% chance of producing long-winged offspring (LW) and a 50% chance of producing short-winged offspring (ww). Therefore, there is a 50% likelihood that the offspring will have long wings.
When crossing two wavy-haired individuals, represented by the alleles W (wavy) and w (straight), a Punnett square would show the possible genotypes of their offspring. The potential combinations would be WW (wavy), Ww (wavy), and ww (straight). Specifically, the Punnett square would yield a 1:2:1 ratio, with 75% of the offspring expected to have wavy hair (either WW or Ww) and 25% with straight hair (ww).
The offspring of a true breeding white flowering plant will also display white flowers because it carries two copies of the white flower gene. These offspring will be homozygous for the white flower trait and will consistently produce white flowers when they reproduce.

The possible phenotypes of offspring from a white rabbit and a black rabbit depend on their genotypes. If the white rabbit is homozygous recessive (ww) and the black rabbit is homozygous dominant (BB), the offspring will all be black (Bb). If the black rabbit is heterozygous (Bb), the offspring could be either black (Bb) or white (ww) in a 3:1 ratio. The specific coat color will depend on the genetic makeup of the parents.
In genetics, widow's peak is typically represented as a dominant trait (W), while a straight hairline is recessive (w). If both parents are heterozygous (Ww), their offspring can be represented by a Punnett square, which shows the possible genotypes: WW, Ww, Ww, and ww. Only the ww genotype results in a straight hairline, which occurs in 1 out of 4 possibilities. Therefore, the probability that two heterozygous parents will have a child with a straight hairline is 25%.
If we cross a homozygous dominant fruit fly with straight wings (WW) and a homozygous recessive fruit fly with curly wings (ww), all offspring in the first generation (F1) will be heterozygous (Ww) and exhibit straight wings. If we then cross two F1 flies (Ww x Ww), the second generation (F2) will show a phenotypic ratio of 3 straight-winged flies to 1 curly-winged fly, resulting in about 75% straight wings and 25% curly wings.
