Answer:
c. RrMm x RrMm
Explanation:
A dihybrid genotype is the one that is heterozygous for two genes. Hence, a dihybrid cross is a cross between two individuals that are hybrid for alleles of two different loci.
Among the given examples, the cross RrMm x RrMm is a dihybrid cross. Here, both given genotypes are heterozygous or hybrid for two loci (both genotypes have one dominant and one recessive allele for both the genes under study, R and r; M and m).
This cross explains the inheritance of two loci or two genetic traits. Hence, it is an example of dihybrid cross.
George Mendel chose to use purebred plants in his experiments because they have a variety of traits.
Releasing insulin to decrease blood sugar and releasing glucagon to increase blood sugar
Photosynthesis is the term for the process by which plants produce food and energy in the presence of some inorganic substances and solar energy.
<h3>What is the reason behind the above answer ?</h3>
The glass of water won't react when it's placed in the sun's rays.
One explanation for the response is: Water and ambient carbon will be the reactants in the experiment, which should produce glucose and oxygen in the presence of the sunbeam.
The true photosynthetic reaction also uses carbon dioxide and water as reactants, but chlorophyll is a plant pigment that is present during the reaction.
