A farmer mates a homozygous tall, red tomato plant (TTRR) with a heterozygous tall, red tomato plant (TtRr). Find the genotypes and phenotypes ratio

Cross between the two will produce following offspring -

TTRR -  homozygous tall, red tomato plant

TTRr - Tall and red

TtRR - Tall and reds

TrRr -Heterozygote  Tall and red

Explanation:

Given -

Genotype of homozygous tall, red tomato plant  is TTRR

Genotype of heterozygous tall, red tomato plant is TtRr

Gametes of TTRR - TR, TR, TR, TR

Gametes of TtRr - TR, Tr, tR, tr

Cross between the two will produce following offspring -

TTRR -  homozygous tall, red tomato plant

TTRr - Tall and red

TtRR - Tall and reds

TrRr -Heterozygous  Tall and red

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
