Answer: the correct answer is 25%
T is the allele for tall plant, which is dominant trait. 't' is the allele for dwarf plant, which is a recessive trait.
Genotypes of the parent plants are- Tt and Tt. When they are crossed, there are 25% chances of producing tt offsprings. Refer the punnett square for this.
% of Offsprings with tt genotype = 
= 25%
If the purple plant is dominant homozygous it should be PP and the if the white flower plant is recessive, it should be pp. If both plants are crossed bred, the possibility will be Pp Pp Pp Pp
Answer:
The frequency of recessive allele should be 0.30.
Explanation:
According to Hardy-Weinberg equilibrium, sum of both dominant allele frequency (p) and recessive allele frequency (q) should be equal to 1 (p+q = 1).
Brown hair = dominant (p)
white hair = recessive (q)
49% mice are brown hair
so dominant genotype frequency = 0.49
According to Hardy-Weinberg principle, square root of the genotype (homozygous) is equal to allele frequency.
√p =√0.49 = 0.70
The dominant allele frequency is 0.7
Now, by this value we can find the recessive allele frequency by
p + q = 1
1 - 0.7 = 0.3
So, the recessive allele (white hair mice) frequency is 0.30.
