Answer:
0.095
Explanation:
Phenylkentonuria is a disease caused by a recessive allele.
The frequency of the recessive allele + the frequency of the dominant allele equals 1.
The frequency of the recessive allele is q = 0.05
The frequency of the dominant allele then is p = 1  - q = 0.95
If people mate randomly, the frequency of the homozygous dominant genotype will be p², the frequency of the heterozygous genotype will be 2pq and the frequency of the homozygous recessive genotype will be q² .
2pq=2× 0.05 × 0.95
2pq=0.095
The heterozygote frequency in the population is 0.095
 
        
             
        
        
        
Answer:
Ben - Y Xc
Jen - XCXC
Violet - XCXc
Seraphina - XCXc
Samuel- Y Xc
Explanation:
Given - 
Ben has a cleft chin 
Let the allele for cleft chin be "c"
and the allele for normal chin be "C"
When Ben with cleft chin mates with wife Jennifer Garner having normal chin, then the two girl child do not have cleft chin but the boy has cleft chin. 
This means that the allele C could be X -linked and the mother is not the carrier but the father is 
The genotype of father Ben would be Y Xc
Genotype of mother would be XCXC
Genotype of two daughters XCXc  , XCXc which means they are carrier for the next generation 
Genotype of Boy - Y Xc
 
        
             
        
        
        
The factors that affect temperature or altitude latitude and distance from sea the height measured from sea level is called altitude when the latitude increases the distance from the Sun Also increases so the temperature gradually decreases
 
        
                    
             
        
        
        
Convective zone is the answer. If you need an explanation just ask.
Hope this helps :)
