Most organisms are Diploid, and as a result, they will have received 2 copies of the chromosomes, or sets of chromosomes, from both their parents. This they will have 2 sets of Genes that will perform almost exact same process, except with different phenotypes.
These chromosomes need to be homologous, in order for new alleles and other genetic combinations to be made.
Answer:
Thymine
Explanation:
Uracil is the nitrogenous base present only in RNA, but not in DNA. ... DNA have thymine, guanine, adenine and cytosine. Thymine is replaced by uracil in RNA.
The main events of prophase are: the condensation of chromosomes, the movement of the centrosomes, the formation of the mitotic spindle, and the beginning of nucleoli break down.
To thrive in censorious I’d the nucleus
I would go with the letter
B- when the frequency of dominant alleles is equal to the frequency of recessive alleles.
Hope that this helps!!! :)
