either one of the two alleles in a diploid individual.
Explanation:
A trait is expressed only when two alleles pair up. Thus, an allele pair during cell division assort independently into two individual alleles so that each gamete receive one of the two allele
For example
During gamete formation XX and XY allele pairs divide to contribute one allele to each gamete respectively.
Thus, XX allele pair will divide to give X gene to both the gamete
And XY pair will divide to give X gene to one gamete and Y gene to other gamete
An operon is a region of RNA that consists of the coding regions of more than one gene.
Explanation:
Operons are clusters of genes that share the same promoter and are transcribed as a single large mRNA that contains multiple structural genes or cistrons.
Pros is that it helps water stay in one place and it also makes water more easily accessed for future use. The cons is animals can have less space to live and the overflow of water can occur which means flooding.
