Tju [1.3M]

Answer:

All the offspring have genotype RrTt

Phenotype is Pink and tall snapdragon

Explanation:

Given

Tallness ( T) is dominant to dwarfness (t)

Red (R) flower color is dominant to white (r)

It is given that heterozygous condition results in pink (Rr) flower color which means that the allels for color of flower show co dominance

Genotype of dwarf red snapdragon is RRtt

Genotype of a plant homozygous for tallness and white flowers is rrTT

The punnet square representing the cross between RRtt and rrTT is as given below-

Rt     Rt         Rt     Rt

rT RrTt      RrTt RrTt    RrTt

rT RrTt      RrTt RrTt    RrTt

rT RrTt      RrTt RrTt    RrTt

rT RrTt      RrTt RrTt    RrTt  

Thus all the offspring have genotype RrTt

Phenotype is Pink and tall snapdragon

irga5000 [103]

By trapping heat, greenhouse gases contribute to our planet's warming. Because of its involvement in the Earth's carbon cycle and nitrogen cycle, the biosphere influences the amounts of some of the major greenhouse gases such as methane, carbon dioxide, and nitrous oxide.
