In certain bacteria, an oval shape (o) is dominant over round (o) and thick cell walls (t) are dominant over thin (t). show a cross between a heterozygous oval, thick cell walled bacteria with a round, thin cell walled bacteria. what are the phenotypes of the f1 and f2 offspring

Phenotypes –  

Oval Thick - OoTt

Oval Thin - Oott

Round Thick - ooTt

Round thin - oott

Explanation:

Given -

Allele "O" is dominant over allele "o"

and allele for thick cell wall "T" is dominant over thin celled wall "t"

Genotype of heterozygous oval, thick cell walled bacteria is OoTt

Genotype of round, thin cell walled bacteria is oott

The cross between the two parents will produce following offspring

OT          Ot      oTot

otOoTtOott      ooTtoott

otOoTtOott      ooTtoott

otOoTtOott      ooTtoott

otOoTtOott      ooTtoott

Phenotypes –  

Oval Thick - OoTt

Oval Thin - Oott

Round Thick - ooTt

Round thin - oott

hey, what do you need . just post the question and i may be able to you : )

i think that you are smart and you should fit for it out
