Yes, it is possible.

In this case both of the parental plants were heterozygotes and they manifested dominant allele in their phenotype, which is round seed.

P: Aa x Aa

F5: AA, Aa, aA, aa - possible genotypes in fifth generations.

A- dominant allele (round seeds); a- recessive allele (wrinkled seeds)

Wrinkled phenotype is manifested only if there are two recessive alleles present.

Which kind of organism does not generally require oxygen or sunlight to live?
gregori [183]
Answer is A.

Archaea requires neither sunlight for photosynthesis as do plants, nor oxygen. Archaea absorbs CO2, N2, or H2S and gives off methane gas as a waste product the same way humans breathe in oxygen and breathe out carbon dioxide. An example is chemosynthetic bacteria by sea drifts. They use chemical energy to produce vital processes to live.

A vaccine works by stimulating the immune system to produce antibodies without actually infecting someone with that disease. They trigger the immune system to produce its own antibodies as though the body has been infected with the disease. But a vaccine will not make someone immune to a disease, it will simply help the body be able fight the infection better.
