The three stages of volcanic activity are active, dormant, and extinct.
Answer:
Father’s phenotype non roller Father’s genotype rr
Mother’s phenotype roller Mother’s genotype Rr
Probability of this couple having a child who is a tongue roller : 1/2
Explanation:
Given that allele for rolling (R) is dominant over allele for non rolling (r).
Since father is a non roller his genotype would be rr
Mother is a heterozygous tongue roller so her genotype would be Rr
Their progeny:
Rr X rr :
R r
r Rr rr
r Rr rr
Half of the offspring have Rr genotype which will make them tongue roller so probability of this couple having a child who is a tongue roller is 1/2.
