Answer:
A. Incomplete dominance.
Explanation:
Incomplete dominance is the ability of two alleles to produce a heterozygous phenotype different from the two homozygous phenotypes.
Example is when a pure stock of red flowered (RR) four o'clock plant is been crossed with a white flowered(rr) one, the offspring are all pink flowered(Rr), showing a blending of flower colour character. Self pollination of the pink flowered F1 individual produce a mixture of F2 individual bearing red, pink and white flowers in the ratio of 1:2:1. This reappearance of the red flowered and white flowered forms in the F2 generation shows that alleles R and r have remained unaltered in the F1 generation.
The answer is taiga.
Taiga is a coniferous forest located in the northern polar subarctic climate zone. What is characteristic for taiga is that winters are very long and very cold. Summers are, on the other hand, short with low temperatures. Many trees in the forest are evergreen conifers with needle-like leaves. <span>Animals have adaptations to seasonal changes by changing their fur or feather color. <span /></span>
They share their experimental results with other researchers
The phenotypes of snapdragons of F1 generation had pink flowers only.
Explanation:
The crossing of snapdragon with red flowers and white flowers as well led to the production of F1 offspring of hybrid quality having pink flowers only. This F1 phenotype under goes pollination and results in F2 phenotype with a ratio of 1 red, 1 white and 2 pink flower.
This is incomplete dominance as the phenotypes of parental plant, as in the white and red flowered plant reappear in the F2 generation.
