Answer:
The answer is 4
Explanation:
The answer is 4 because we are talking about pairs of homologous chromosomes and there two copies are held together and they are located in the centromere.
Synapsis is two homologous chromosomes pairing. During the event of <em>meiosis </em>homologous chromosomes are being pared but then also separated because of reducing the genetic content of the resulting haploid cells.
They are less likely to be separated during crossing over.
Answer:
Option-D, a segment of DNA
Explanation:
A gene represents the particular segment of DNA which contains the instruction for the trait of an organism. The nucleotide sequence present in the segment provides the instruction in the form of codons.
The gene is present in the form of its alternative form called alleles which are located on the chromosomes at locus. The alleles represent the variants of the gene and therefore controls the two variety of a single trait.
Thus, Option-D is correct.
Antigens determine blood type
Prokaryotes reproduce by *BINARY FISSION* which creates *2*exact daughter cell clone(s) of the original parent cell.
