A tall pea plant (Tt) is crossbred with a short pea plant (tt). The following Punnett square shows the separated alleles for two pea plants. Punnett square showing female parent across the top with a phenotype of tall and a genotype of Tt and a male parent across the side with a phenotype of short and a genotype of tt. Inside the top left box 1 is written, inside the top right box 2 is written, inside the bottom left box 3 is written, inside the bottom right box 4 is written.

Which of the following shows the correct match of the box numbers and the genotype of the offspring? (3 points)

a
1 = Tt; 2 = tt; 3 = Tt; 4 = tt

b
1 = Tt; 2 = Tt; 3 = Tt; 4 = Tt

c
1 = Tt; 2 = Tt; 3 = tt; 4 = tt

d
1 = Tt; 2 = tt; 3 = tt; 4 = tt

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.

The answer is energy. the arrows are showing how exited and energized the stones are.
