<span>The importance of the G0 phase is that during cell division when the cell get a signal that there are enough of cells (not more required) or there is a mutation in the cell that need to be fixed before they differentiate fully or the cell during its division gets damage then it is signalled to rest, and it is this phase that cell leave the cycle and quit dividing. It could be temporary resting period (so when cell again required, or damaged got fixed) then the cells will again join the cycle and continue to divide again or it can also be permanent for example neurons, which are resting in G0 phase and never divides again.</span>
The process of cellular division by which gametes are formed is called Meiosis. The process occurs in specialized cells of the body called the germline cells, where gametes with half the normal chromosomes number (haploid) are produces. During fertilization the gametes each with haploid number combine to form a diploid zygote.
Answer:
The given statement is false.
Explanation:
The lateral gene transfer of the horizontal gene transfer refers to the movement of the genetic substance between the multicellular and unicellular organisms other than by the vertical transmission of DNA to the offspring from the parent. Horizontal gene transfer is essential for evolution in several organisms. The mechanism is common among the prokaryotes like bacteria and is accountable for bacterial drug resistance.
On the evaluation of certain sequences of DNA, it has come to know that horizontal gene transfer also takes place in eukaryotes from the mitochondrial and chloroplast genomes to the nuclear genome. One of the examples is that plants possess the tendency of getting genetic information from viruses.
Answer:
A. Variably expressive and incompletely penetrant
Explanation:
Incompletely penetrant is a genetic term which means the genetic trait is visible in a fraction of people.
Variable expressivity is the range of signs and symptoms developed in different people with the same genetic condition.
Only some of the members who have inherited the mutant allele have a second toe longer than the big toe signifies variably expressive trait while the extent of webbing varying signifies incomplete penetrant.
