Explanation;
Yellow seed color (dominant)
Green seed color (recessive)
P generation: In Mendel's experiments the parental generation.
Yellow seed color

Answer:
Incomplete dominance
Co-dominance
Explanation:
Gregor Mendel discovered the principles that governs heredity, in which one of them is that an allele called DOMINANT allele, is capable of masking the expression of its variant allele called RECESSIVE allele in a heterozygous state. However, there has been genetic scenarios contrary to this his LAW OF DOMINANCE.
One of those Non-mendelian pattern of inheritance is a phenomenon called INCOMPLETE DOMINANCE, where an allele does not mask the expression of another completely, instead their combined state produces a third intermediate phenotype that is different from both parents. This is the case of the homozygous black bull mated with a homozygous white cow to produce a grey calf. The grey phenotype is an intermediate phenotype of both the black and white colours that forms due to incomplete dominance.
Another genetic scenario is called CO-DOMINANCE, where one allele is neither dominant nor recessive to the other allele, but instead both phenotypes becomes simultaneously expressed in the heterozygous offspring. In this case, the black bull and white cow were mated to form a heterozygous calf with both black and white spots.
The discovery of DNA, as well as understanding of its functioning and structure, may well be the most essential findings of the last century.
The impact of the discovery of DNA on medical and scientific advancement has been huge, whether it involves the manufacturing and creation of drugs to cure the deadly diseases or to identify the genes, which stimulate several of the diseases.
The understanding of DNA and its structural composition has led to the discovery of various technologies that helps in the fields like genetic testing, identifying viruses, crime investigation, production of genetically modified organisms, and various others.
All cells share four common components:<span>a plasma membrane: an outer covering that separates the cell's interior from its surrounding environment.cytoplasm: a jelly-like cytosol within the cell in which other cellular components are found.DNA: the genetic material of the cell.<span>ribosomes: where protein synthesis occurs.</span></span>
