Question

A. Read and analyze the following genetic problem. Answer what is being asked. Show complete solution in a separate paper then take a picture and upload it here.(Genotypes of P, Punnett Square and GR, PR).

2. If you crossed a heterozygous spotted lizard with a homozygous green lizard, what percentage of their offspring would be green and what percentage would be spotted? Note: You may use your own letters to signify the alleles.

Answer 1

Homozygous deep = ss

Homozygous shallow=SS

Cross is made between deep and shallow for F1 generation

SS x ss

Genotype= all Ss

Phenotype=Shallow

If self pollination is allowed between F1 generation plant

F2 generation

Genotypic = 1 : 2 : 1 or 1/4 SS: 1/2 Ss: 1/4 ss

Phenotypic = 3 : 1 or 3/4 shallow; 1/4 deep
