10 Questions
Which of the following is true about the modified allele?
It may produce the normal/less efficient enzyme, a non-functional enzyme, or no enzyme at all.
What is the effect of the modified allele on the phenotype?
It may be affected if the allele produces a non-functional enzyme or no enzyme.
Which allele represents the original phenotype?
The unmodified allele.
What is the relationship between the dominant and recessive alleles?
The dominant allele is generally the unmodified allele.
Why is the recessive trait seen in the example above?
Because the modified allele produces no enzyme at all.
Which gene controls ABO blood grouping in human beings?
Gene I
How many alleles does the gene I have?
Three
Which allele does not produce any sugar?
i
Which alleles are completely dominant over i?
I A and I B
What happens when I A and I B are present?
Both alleles express equally
This quiz explores the theoretical possibilities of a modified allele in inheritance and variation. Learn about the different outcomes it can produce, such as normal/less efficient enzyme production, non-functional enzyme production, or no enzyme production at all. Discover how these variations can affect the phenotype and transformation of substrate S.
