The genetic base of the shape of orchid is very complex.
Mendelian traits are described as simple traits determined by one gene. The different alleles of the gene contribute to the difference in the trait. This is true for some traits in plants, animals including humans and other organisms, but not for the shape of orchids.
The shape of orchid flowers is determined by the ABCDE group of genes that are responsible for the body plan in plants. These genes are the equivalent of HOX genes of animals.
The protein products of different genes of the ABCDE group interact with each other in complex ways creating different shapes of orchids.
Answer:
The orchids derive nutrients from the association at very young stages of its life cycle while the fungi obtain water and organic matter
Explanation:
As stated in this question, fungi species belonging to the phylum Basidiomycota form mycorrhizal associations with a flowering plant called orchids. This relationship is a mutualistic one because both participants benefit from the relationship.
In this association, the young orchid plant relies on the mycorrhizal fungi's metabolism to get nutrients needed for its development in form of carbohydrates while the fungi in return gets water (from the roots of the plant) and organic matter.
The evidence that best supports conversation during photosynthesis is: Light energy is converted to chemical energy during photosynthesis ( A )
Photosynthesis is the process whereby plants make use of water and carbon dioxide found in the atmosphere to transform/convert the light energy from the sun into chemical energy.in the process of synthesizing food
The products of photosynthesis include oxygen and glucose while the conversion during photosynthesis takes place when the chloroplast absorbs the light energy from the sunlight and converts it another form of energy ( chemical energy ).
Hence we can conclude that The evidence that best supports conversation during photosynthesis is ; Light energy is converted to chemical energy during photosynthesis.

The evolution of apes to man
Answer:
C.
Explanation:
Diploid and polypeptide cells whose chromosomes have the same allele at a given locus are called homologous with respect to that locus, while those that have different alleles at a given locus are called heterogeneous. The ordered list of loci known for a particular genome is called a gene map.
