Answer:
A punnet square can be described as a diagram which is made to check the outcomes of a cross.
To check the probability of the offsprings of a cross between homozygous dominant thumb shape parent with a homozygous recessive thumb shape parent, let's draw a punnet square:
t t
T Tt Tt
T Tt Tt
The results of the punnet square depict that:
Genotype: All of the offsprings will be heterozygous for the thumb shape trait. Tt will be the genotype.
Phenotype: All of the offsprings will show the thumb shape like the thumb shape of the dominant parent.

Oxygen is an abiotic factor that is beneficial by-product of primary production.
<u>Explanation:</u>
The non living parts of an ecosystem that mainly affects the living organisms in it are called as an abiotic factor. These can include soil, temperature, water, oxygen and sunlight. The major energy source in earth is Oxygen which is abiotic factor.
It is very essential for the photosynthesis process to take place. Here, the plants converts water and carbon dioxide into oxygen and sugar. This becomes food for plants. Then these plants are eaten by animals. Thus oxygen is an important and beneficial by-product of photosynthesis. Oxygen is also very important for the survival of human beings.
