Answer:
The atomic number is equal to the number of protons in an atom's nucleus. The atomic number determines which element an atom is. For example, any atom that contains exactly 47 protons in its nucleus is an atom of silver.

Answer:
a) Genotype of each parent plant= Tt
b) Genotypes of parent plants= Tt and tt
Explanation:
a) In the first cross, the tall and short progeny was obtained in almost a 3:1 ratio (78: 27). This means that both the parent plants were heterozygous for the gene of plant height. The genotype of each of the parents was Tt. A cross between Tt and Tt gives following progeny ratio=
Tt x Tt = 3 tall (1/2 TT and 1/4 Tt) : 1 short (1/4 tt)
b) In the second cross, tall and short progeny was obtained in almost a 1: 1 ratio (121: 118). This means that one parent plant was homozygous recessive (tt) and the other was heterozygous dominant (Tt).
Tt x tt = 1 tall: 1 short.
The phenotype of the parents will be all red.
The monohybrid snapdragons are generating red and white seeds in the ratio 3: 1 with the white (r) phenotype being recessive and the red (R) phenotype being dominant. Thus, they would possibly have the parents exhibiting genotypes, Rr and Rr, that is, both red.
The gametes generated by these parents are R and r. The cross of these parents will lead to the formation of the following generation shown in the cross below, that is, in the ratio 3: 1 (red: white).
