Grant's research was made on medium-sized finches on the Galapagos islands showed evolutionary processes in real-time. He showed that due to the drought there is a decrease in the number of small and soft seeds that were finches major food source.

It is known that there are different beak sizes in this finch species, the finches with larger beaks could feed on tough and large seeds and survive in such case of the drought-induced decrease in food availability.

The incidence of Down syndrome, also known as trisomy 21, increases with increasing maternal age. Which of the following errors
Naily [24]

Answer:. Nondisjunction during meiosis I in either the male and female gamete

The failure of   homologous chromosome to separate at mitosis,  or failure of sister chromatids  to separate at Anaphase of  meiosis I or ii is called  non-disjunction.

 In this  cell division anomaly the  unsegregated chromosomes  are  separated  into  cells as single chromosomes, therefore extra copies are  therefore inherited.This  result is one of the cell having an extra copies of  chromosomes than others( chromosomes 21.

If this extra  chromosome copies  is segregated into a sperm or egg, the resulting zygote cells will   have extra  copy as  chromosome 21, and hence Down syndrome.

→It is more common in Meiosis 1 than ii,because of longer duration of the first stage of division than meiosis ii,given rooms to errors.

→Most common in women(with age increase)  than men because of exchange of telomeres in   them,which  worsen with age. Their Meiotic mechanism  which   weaken with age, and  more prone to errors compare to men,
