The plants ploidy is decided based on the chromosome within the nucleus . Plant can be either heterozygous or homozygous.
The major distinction between homozygous and heterozygous individuals is that the former have two identical alleles while the latter have both dominant and recessive alleles. Over several generations, kids with the same characteristic are produced through self-breeding between homozygous individuals.
Heterozygous and homozygous chromosomes are seen in human beings. Allele pairings are categorized as Heterozygous and Homozygous. A heterozygous person possesses various alleles, whereas a homozygous person carries a pair of identical (RR or rr) alleles (Rr).
Let's take the gene for hair colour as an example. This gene has two alleles, one of which is responsible for black (r), and the other for black (R). On a homologous set of chromosomes, such as RR or rr, homozygous people will carry the same colour allele, but heterozygous people will carry distinct colour alleles.
Hence, depending on type allele can be homozygous or heterozygous.

Science study the life cycle of pathogens in order to find a way to interrupt the course of disease and spread of infection. Scientist study the life cycle of microorganism in order to find a way to cancer and other chronic illness.
Explanation:
The life cycle of microorganisms causing disease in the human is studied to know what agents or antibiotics would stop their activity. There are techniques used such as chemotherapy to kill the invading viruses. The antibiotics are made this way to stop bacterial growth. The agents would be invented to put stop at the particular phase of the life cycle to inhibit growth of the pathogen. It would get convenient to make agents if at immune level it is known what phase of their cycle is reactive.
Answer: Natural selection can act on traits determined by alternative alleles of a single gene ... hope this helps, this is one of many answers for this question!
