Alleles refer to the DNA!! So B!
Photosynthesis allows plants to take in sunlight, water, and carbon dioxide to make energy for themselves, a type of sugar called glucose.
Glucose =
The other thing that is made from photosynthesis is oxygen.
Without oxygen, we would not be able to live on earth.
Hope this helps!
Answer:
In mendelian inheritance, the alleles for a gene show normal dominant-recessive relationship. Chromosomes also show crossover due to which new random combination of traits is possible in the offspring. This crossover takes place between homologous chromosomes during meiosis I.
Organellar DNA like the ones present in mitochondria and chloroplast do not follow mendelian inheritance because unlike nuclear chromosomes they do not have cross over events. There is no orderly segregation of alleles during meiosis. Traits controlled by them are usually inherited as it is and usually it is from the maternal parent because paternal gamete like sperm does not contain mitochondria.
