The progression of a cell by the cycle of cell is regulated by the protein family Cyclic
Explanation:
- In the year 1982, Cyclin was located by Timothy Hunt as a family of proteins which has a vital function in the progression of a cell. 
- CDK enzymes or ‘cyclin dependent kinase’ gets activated by it that synthesizes the cycle of the cell. 
- The concentration of this protein moves in a cyclic way in the cell cycle. No enzymatic function is seen in them but it aims at CDK’s different location.
 
        
             
        
        
        
If two heterozygous individuals are crossed, the results of the cross are as follows:
- SS - spotted condition
- 2 Ss - Spotted condition 
- ss - non-spotted condition
<h3>What is an Heterozygous Cross:</h3>
According to this question, the gene coding for spotted condition. The allele for spotted condition (S) is dominant over the non-spotted condition (s). 
If two heterozygous Dalmatian dogs are crossed i.e. Ss × Ss, the allele combination for each gamete is as follows:
The following offsprings will be produced: 
- SS - spotted condition
- 2 Ss - Spotted condition 
- ss - non-spotted condition
