Answer:
The chromosomes have coiled and become more compact.
Explanation:
The answer is
frequency of the homozygous recessive genotype --> q^2
frequency of the heterozygous recessive genotype --> 2pq
frequency of the recessive allele --> q
frequency of the dominant allele --> p
frequency of the homozygous dominant genotype --> p^2
Hope this will help for all
Dominance involves one allele masking another at the same locus whereas epistasis involves one locus masking a different locus.
Explanation:
Epistasis is a type of gene interaction in which one gene masks or modifies the expression of another gene at a distinct locus.
Dominance refers to the gene interaction in which one allele of a given gene masks the expression of another alllele of same gene.
The comparison of dominance and epistasis give the following information:
- Dominance involves allelic suppression while epistasis involves non-allelic suppression.
- Dominance involves a single pair of alleles while epistasis involves two pairs of allele.
- In dominance, the expression of recessive allele is suppressed while in epistasis, either recessive or dominant non allele is suppressed.
- The effect of dominance is due to the dominant allele while epistasis may be due to dominant or recessive allele.
