Answer:
A. dihybrid crosses
Explanation:
A dihybrid cross can be defined as a mating experiment between two lines/varieties/organisms that differ in two phenotypic traits. By using pea plants, Mendel performed dihybrid crosses in order to analyze the mode of inheritance of both phenotypic traits at the same time. From these mating experiments, Mendel observed that the inheritance factors (nowadays called genes) sorted independently from one another in the next generation, which is called the principle/law of Independent Assortment.

Well for starters, producers are living organisms that produce their own food. Like plants. And plants ironically provide us humans with oxygen as they live off of the carbon dioxide we produce. Some plants are also main vegetables that we eat, so put simply, a world without producers would be practically oxygen-less and vegetable-less.
        
             
        
        
        
Answer:
The answer is alleles :)
Explanation:
The two versions of the same gene are called alleles. The two alleles are formed at the same position, or locus, on the chromosome. REMEMBER: THE 2 ALLELES ARE GOTTEN FROM THE 2 GAMETES OF SEXUAL REPRODUCTION. THAT IS WHY THEY CAN DIFFER.
I hope I helped you !
