The probability of generating plants with white axial flowers is 1/16. Based on the given illustration, all F1 offspring exhibited red axial flowers, indicating that the genes for red and axial traits are dominant over those for white and terminal traits in pea plants. Let's denote the allele for flower color as A (red) and a (white), and for flower position as B (axial) and b (terminal). The genotype of pure-breeding red axial flowers would be AABB, while pure-breeding white terminal flowers are represented as aabb. Crossing these results in F1 genotype AaBb, which shows all red axial flowers. For the F2 generation from AaBb crossed with AaBb, the progeny breakdown is: 9 A_B_ red/axial, 3 A_bb red/terminal, 3 aaB_ white/axial, and 1 aabb white/terminal. Consequently, the chance of generating plants with white axial flowers in the F2 generation is 1/16.

The higher an animal is positioned on a cladogram, the more closely it is related to other animals.
An individual who possesses two identical X chromosomes is female.
Since women have a pair of X chromosomes, they are considered homozygous for the X chromosome - the term homozygous refers to having 'two chromosomes of the same type.' In contrast, men typically have different chromosome types - XY.
