I’m not sure what your asking. But if you have 2 different alleles of a gene it will be heterozygous
Answer:
The correct answer will be option A.
Explanation:
The bacteria organize its genetic material in the single circular chromosome suspended in the cytosol along with additional circular double-stranded DNA molecule called plasmid.
The plasmid is present as a separate structure in the cytoplasm which performs important functions during stressful conditions in the bacteria like providing antibiotic resistance to the bacteria, formation of filial factors during conjugation and many others.
The plasmid which confers resistant to the bacteria is known as the R-plasmid. The R-plasmid consists of r-determinants which confers antibiotic resistance to the bacteria and resistance transfer factor (RTF) which helps in plasmid transfer.
Thus, option A is the correct answer.
Natural selection doesn't favor traits that are somehow inherently superior. Instead, it favors traits that are beneficial (that is, help an organism survive and reproduce more effectively than its peers) in a specific environment. Traits that are helpful in one environment might actually be harmful in another.
(one again, I hope this helps ^^)
Answer:
B. misalignment of the chromosomes during anaphase I
Explanation:
Aneuploidy refers to an error in the chromosomal number of a cell. This occurs when the chromosomes fail to separate equally into individual cells, a process called MEIOTIC NONDISJUNCTION. Meiotic disjunction can occur in either the anaphase stage of meiosis I or meiosis II, however, different outcomes are produced.
When chromosomes fail to separate at meiosis I, it results in two gametes that lack that particular chromosome (n-1) and two gametes with two copies of the chromosome (n+1). This means that the four daughter cells will have an incorrect number of chromosomes, hence, the misalignment of the chromosomes during anaphase I will result in four aneuploid daughter cells.
I think it’s “a Protein molecule”
