Here we would be using Hardy Weinberg equation for the calculation of allele and genotypic frequencies.
Dwarf genotype frequency = 
= 25% = 0.25
Frequency of allele t = q = 
= 
= 0.5
According to the equation,
p + q = 1
p = 1 - 0.5 = 0.5
Now, the frequency of heterozygous tall plants would be-
2pq = 2 * 0.5 * 0.5 = 0.5 or <u>50% heterozygous tall plants</u>.
Since males have only x-chromosome they are more likely to express x-linked (by far the most common type of sex - linked disorders ) recessive traits. females can also not express any y-linked traits. females have a backup copy of the genes on their other x-chromosome, similar to autosomal chromosomes.
