Which of the following statements is true about moss and fern reproduction?

Biology
1 answer:
DiKsa [7]3 years ago
4 0

The answer is; Both mosses and ferns have a dominant gametophyte generation.

The gametophyte is the phase in the life cycle of the plant where it is in the haploid phase and produces gametes. This phase also develops from a haploid spore. When the gametophyte produces spores, the gametes, in ferns and moss require water (because the spores have flagella to swim). The gametes meet and fuse to form a zygote that develops into the sporophyte phase of the plants. In higher plants, the sporophyte is the dominant phase.

AleksAgata [21]

Answer:

Epistasis

Explanation:

In epistasis, the interaction between genes is inimical, such that one gene masks or interferes with the expression of another. “Epistasis” is a word coined of Greek roots that mean “standing upon.” The alleles that are being masked or silenced are said to be hypostatic to the epistatic alleles that are doing the masking. The cause of the biochemical basis of epistasis is a genetic pathway in which the expression of one gene is dependent on the function of a gene that precedes or follows it in the pathway.

The example of epistasis given is the pigmentation of mice. we were told that "if a mouse has two recessive alleles for coat color,  it is always albino no matter what the genotype of other genes involved in coat color"

Let say recessive allele (rr), it is always albino irrespective of other type of other genes, this is true in the stance that epistasis can be reciprocal such that either gene, when present in the dominant (or recessive) form, expresses the same genotype.
