Answer:
Gametophyte,sporophyte.
Explanation:
The gametes produce by gametophyte is contain in Anther and ovaries and sporophyte develops into zygote(plant).
Sporophyte through meiosis produces spores. Meiosis been a reductional process reduced the 2n to n(haploid chromosome).
The haploid spores formed germinate into haploid gametophyte.
Gametophyte at maturity produces gametes through mitosis. Two gametes from similar organism or organism of the same species then fuse together to produce zygote
A ballad poem is <span>a poem or song narrating a story in short stanzas. It is a </span>popular narrative song passed down orally. In the English tradition, it usually follows a form of rhymed (abcb) quatrains<span> alternating four-stress and three-stress lines. Folk (or traditional) ballads are anonymous and recount tragic, comic, or heroic stories with emphasis on a central dramatic event.

Answer:
1. A plant of genotype
is testcrossed to
If the two loci are 10 m.u. apart, what proportion of progeny will be A B/a b?
45 percent of the progeny will be A B/a b
2. The A locus and the D locus are so tightly linked that no recombination is ever observed between them. If A d/A d is crossed to a D/a D, and the F1 is intercrossed, what phenotypes will be seen in the F2 and in what proportions?
P A d/A d × a D/a D
F1 A d/a D
F2 1 A d/A d
2 A d/a D
1 a D/a D
3. The R and S loci are 35 m.u. apart. If a plant of genotype
is selfed, what progeny phenotypes will be seen and in what proportions?
4. The cross E/E · F/F × e/e · f/f is made, and the F1 is then backcrossed to the recessive parent. The progeny genotypes are inferred from the phenotypes. The progeny genotypes, written as the gametic contributions of the heterozygous parent, are in the following proportions:
Explain these results.
The two genes are 33.3 map units (m.u.) apart.
5. A strain of Neurospora with the genotype H · I is crossed with a strain with the genotype h · i. Half the progeny are H · I, and half are h · i. Explain how this is possible.
Because only parental types were recovered, the two genes must be quite close to each other, making recombination quite rare.
Explanation:
Answer:
HYDRA
Explanation:
The nerve cells are scattered in each layer of the body wall and these neurons send information from sensory organs. Based on the given choices above, the organism that has a nerve net that allows it to respond to a stimulus in a coordinated way is the HYDRA.
Two organisms of the same species are much closer. This is because a kingdom is all organisms and environments put together while a species are very similar down to their gene pools.
