Question

Number of chromosomes in meiocyte, egg
and endosperm of maize is respectively
(1).10,5 & 15
(2).20,10,20
(3).20, 10,30
(4).16, 8, 24​

Answer 1

Answer:

the answer is 20, 10,30 approx

Answer 2

Answer:

Meiocyte chromosomes are 20, eggs are 10, and endosperm is 30 in numbers in maize.  

Explanation:

• When the meiocyte contains 20 chromosomes the number of gamates are half of it that is, 10 (2n = 20; n = 10); while the endosperms are triploid $(3 n=10 \times 3=30).$
• As, we have the known fact that embryo is diploid. It is 20 chromosomes $(2 \times 10=20)$ for a maize grain. It all depends on our chromosome assumption.
