Question

question 6
an allele that will cause a trait to be exhibited if it is heterozygous or homozygous is called
○ the lower case letter
○ recessive
○ dominant
○ a mutation
question 7
1 pts
an allele that only causes a trait to be exhibited when it is homozygous is
○ the upper case letter
○ recessive
○ dominant
○ a mutation

Explanation:

For Question 6: By genetic definition, a dominant allele expresses its associated trait in both heterozygous (one dominant + one recessive allele) and homozygous (two dominant alleles) genotypes. Lower case letters represent recessive alleles, recessive alleles only show traits in homozygous form, and mutations are changes in genetic material, not the term for this expression pattern.
For Question 7: A recessive allele only manifests its trait when present in a homozygous state (two copies of the recessive allele). Upper case letters represent dominant alleles, dominant alleles show traits in both homozygous and heterozygous states, and mutations are genetic changes, not this expression type.

Answer:

Question 6: dominant
Question 7: recessive
