A gardener crosses a true-breeding tall tomato plant bearing red fruit with a true-breeding dwarf tomato plant with yellow fruit
Lemur [1.5K]

Cross of true breeding dominant and recessive tomato plants will have:

Phenotype ratio in F1 generation is 4:0

genotype ratio in F1 generation is 4:0.

Explanation:

Data given:

Tall vine = dominant TT

dwarf vine = recessive tt

red fruit dominant  RR

yellow fruit recessive   rr

true breeding tall tomato plant bearing red fruit is TTRR

true breeding dwarf tomato plant bearing yellow fruit = ttrr

the cross is shown in punnet square:

      TR       TR

tr    TtRr    TtRr

tr  TtRr    TtRr

the phenotype ratio- 4:0

the genotype ratio - 4:0

The phenotype is tall vine with red fruit

Genotype is all the progeny are heterozygous dominant.

Which organism is NOT made up of 1or more eukaryotic cells?
nalin [4]

Answer:

D

Explanation:

Methanogens are prokaryotes and therefore have prokaryotic cells. They are single-celled archaea. They are found in hypoxic conditions like the first stomach of ruminants where they digest molecules like cellulose and produce methane as a byproduct. The rest are composed of eukaryotic cells which are much larger than prokaryotic cells and their organelles are membrane-bound (unlike prokaryotes).
