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.
I believe it is DNA replication
Water is one agent of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away.
