Question

If stock contains 58 chromosomes and scion contains 30 chromosomes then how many chromosomes are present in root and egg cell of resultant plant respectively

Answer 1

Answer:

the root will have 58 chromosomes because the root of stock is present whereas the scion's branch is only connected in the resultant plant

and the egg will have 29

Answer 2

ANSWER:

The plant part containing strong root system is called stock.

The plant part containing better flower, fruit yield is called scion.

The chromosome no. remains the same in root cells but is reduced to half in egg cell borne in flower.

So, if the scion contains 30 chromosomes the egg cell will be a haploid of it i.e. it will contain 15 chromosomes.

Also, if the stock contains 58 chromosomes the root cells will have 58 chromosomes.
