Answer:
genetics
Explanation:
calico cats must also inherit a gene unrelated to the X and Y chromosomes that codes for white fur. Because male cats have one X chromosome with code for black or orange and one Y chromosome with no color genes, they cannot technically be calico. About one in every 3,000 calico cats is born a male, and, unfortunately, don't live as long as female calicos due to their genetic abnormalities. XXY Syndrome renders male calicos sterile and can be the root cause of many other health problems
Answer:
Nitrogen fixation
Explanation:
Biological nitrogen fixation is carried out by two types of microorganisms namely, symbiotic and free living microorganisms. Symbiotic microorganisms are bacteria f the genus <em>Rhizobium</em>. These are found in root nodules of leguminous plants. They convert atmospheric nitrogen into ammonia which is used directly by leguminous plants to form nitrogen containing organic compounds.
Pollen contains the male gamete.
The pollen from one plant is transferred to the stigma of another plant of the same species. Stigma is the female part.
