Answer:
So that in a guinea pig cross in the offspring the recessive trait —long hair— can be observed in 25%, the most probable genotype of the parents is heterozygous Ss.
Explanation:
In guinea pigs, for the characteristic<u> hair length, short hair is the dominant allele and long hair is the recessive one</u>.
In order for 25% of the offspring to express the recessive characteristic, the parents must have a recessive genotype, which can be seen in Punnett's Square:
P: <u>Ss X Ss
</u>
<em>Alleles     S     s
</em>
<em>S             SS   Ss
</em>
<em>s             Ss    ss
</em>
Where the offspring is:
- <em>50% Ss with short hair phenotype
</em>
- <em>25% SS with short hair phenotype
</em>
- <em>25% ss whose phenotype would be long hair.
</em>
According to this, heterozygous parents for the characteristic long hair in guinea pigs have a 25% chance of having offspring with long hair.

Answer:
Explanation:
Carbonic anhydrase modification is a promising strategy for improving the potency and stability of carbonic anhydrase, which is used to expedite CO2 uptake from flue gases. Carbonic anhydrase can be genetically engineered to increase CO2 conversion, absorption of CO2 from a gaseous state into bioactive compounds, and mineral synthesis.
When carbonic anhydrase attaches to a ribosome, the carbonic anhydrase will now be synthesized at first by the free ribosome, after which the ribosome will become a bound ribosome and the protein will be present in the rough Endoplasmic reticulum when the synthesis is complete.
 
        
             
        
        
        
Answer:
Rr x rr
Explanation:
Let's say 
RR is a tall plant.
Rr is tall
& rr is a small plant
The only genotypes you can get to make two tall and two short is if you use a  hetero pair and a same ressesive (rr) genes.
