Answer:

double-stranded RNA (dsRNA) homologous to the gene of interest

Explanation:

RNA interference (RNAi) is a naturally occurring mechanism used by eukaryotic cells to suppress gene expression through regulatory non-coding RNAs (e.g., small interfering RNAs, siRNAs) that are complementary to the target gene of interest. These non-coding RNAs can bind to target messenger RNAs (mRNAs) in the cytoplasm in order to trigger mRNA degradation and/or block translation. The RNAi mechanism is widely used in molecular biology laboratories in order to inhibit the expression of target genes and thus understand gene function. The RNAi mechanism can be induced by transfecting into cells long double-stranded RNA (dsRNA) molecules that are complementary to the target mRNA sequence to be degraded. RNAi is initiated by the enzyme Dicer that cleaves dsRNAs into siRNAs (19 to 25 nucleotides), which are then incorporated into an RNA-induced silencing complex (RISC) in order to suppress gene expression at the post-transcriptional level (i.e., the mRNA is degraded after transcription).

FinnZ [79.3K]

Answer:

PP = 25%

Pp = 50%

pp = 25%

Explanation:

Using punnett square, we can predict the percentage probability of genotypes.

P p

P PP Pp

p Pp pp

In this cross we have,

PP = 1/4 = 25%

Pp = 2/4 = 50%

pp = 1/4 = 25%

We have ratio,

1 : 2 : 1

In a population of birds some individuals are born with thicker, stronger beaks than others. This is a trait that is inherited.

C)The two species cannot have viable offspring together.

An ecological niche can be defined as the functional role played by the organism or species in order to survive in it's habitat. Like the type of food consumed by the organism, type of mating mating season and others.

In the given situation, the thick beak birds likely to develop in a new species because of this typically adaptation. The two species may exhibit reproductive isolation as they may not be capable of inbreeding among themselves and cannot produce viable offspring together.
