Period can be of a second,minute,hour or of Some years.We will give unit according to the duration of time.In the given options second is most obvious because it is used to measure time.
There is only one kind of gamete formed by an individual who is homozygous at that particular locus.
<h3>What is the law of segregation? </h3>
Gregor Mendel investigated the trait inheritance in pea plants. He put up a theory in which attributes were determined by pairs of "heritable elements," or genes. Alleles, which are various variants of a gene, exist.
The appearance of the organism is determined by a dominant allele, which conceals a recessive gene. Each gamete produced by an organism has a single gene copy that is chosen at random.
The genotypes (allele combinations) and phenotypes (observable qualities) of progeny from genetic crossings may be predicted using a Punnett square. An organism with a dominant trait can be tested to see if it is homozygous or heterozygous using a test cross.
Therefore, only one kind of gamete will be formed by an organism that is homozygous at that particular locus.

Answer: Genetic exchanges among bacteria occur by several mechanisms. In transformation, the recipient bacterium takes up extracellular donor DNA. In transduction, donor DNA packaged in a bacteriophage infects the recipient bacterium. In conjugation, the donor bacterium transfers DNA to the recipient by mating.
