If a cross is made between the plants having TT (tall) and tt (dwarf) genetic
composition, which type of plants we will obtain in the next generation?

Answer 1

Answer:

Explanation:The alleles (= forms) of the gene for height are the same in true breeding plants ( T T and t t parent plants ). Cross breeding T T with t t plants produces T t plants in the first or F1 generation. The F1 plants receive a T allele from the tall parent and a t allele from the short parent.

Answer 2

In the next generation all the plants will be heterozygous tall ie Genotype of Tt and phenotype is all tall.

Explanation:

The alleles for the tall plant is given as TT, as they are dominant.

the alleles for the dwarf plant is given as tt, as they are recessive.

The cross between them and the results in first filial generation is

TT  X tt

Tt, Tt, Tt, Tt

We can see that in cross between the tall and dwarf plants all the plants are heterozygous tall.

Genotype and phenotype ratio is 4:1
