Answer:
75%
Explanation:
Tall stems are dominant over short stems. Let T represent tall and t represents short. The parents are Heterozygous tall plants, which means that their genotype would be Tt and their phenotype would be tall. In a Punnett square it would look like this:
T t
T TT Tt
t Tt tt
Notice that we have 3 possible genotype combinations. When the dominant allele T is present that means that the phenotype that will be expressed is the dominant trait. In this case we have the following genotype and phenotype:
TT Tall 1/4
Tt Tall 2/4
tt Short 1/4
The question is asking the chance the pffspring phenotype is the same as the parent specifically so we can see that 3/4 are tall.
3/4 = 75%
The study of genes and inheritance is called genetics. There are two types of alleles and these are recessive and dominant.
The correct answer is 75%.
What are genes?
- A gene is a basic unit of heredity and a sequence of nucleotides in DNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA.
- The RNA can be directly functional or be the intermediate template for a protein that performs a function

The question is asking the chance the offspring phenotype is the same as the parent specifically so we can see that 3/4 are tall.
Hence, the correct is 3/4 = 75%.
