In the society of clones, human clone lacks traits necessary for true independence from "parent" cells.

<u>Explanation:</u>

. In pea plants, the allele for tall plants (T) is dominant to the allele for short plants (t). You observe that the offspring o

sasho [114]

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.
