Answer:
Dwarf plants should be 20
Tall plants should be 60
Explanation:
This question involves a single gene coding for height in pea plants. The tall allele (T) is dominant over the allele (t). This means that T will always mask the expression of t in a heterozygous state.
Heterozygous state implies a plant that contains both dominant and recessive alleles i.e. Tt. Using a punnet square, two heterozygous pea plants (Tt × Tt) will produce four possible offsprings with genotypes: TT, Tt, Tt and tt.
TT, Tt, Tt are all phenotypically tall while the are phenotypically dwarf. Hence, a 3 Tall : 1 dwarf ratio was obtained. The phenotypic ratio can be used to determine the amount expected in offsprings.
Out of 80 offsprings, 1/4 × 80 will be dwarf i.e. 20
Out of same 80 offsprings, 3/4 × 80 = 60 will be produced.
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. Mark me brainliest please?
