What would be the number of chromosomes in endosperm layer?

What is the chromosome set of an endosperm?

Each nucleus within the pollen tube contains one haploid set of chromosomes. The egg also contains a haploid set of chromosomes, while the zygote is diploid (with 2 sets of chromosomes) and the endosperm is triploid (with 3 sets of chromosomes).

What would be the number of chromosomes respectively in the cells of aleurone layer and endosperm in a flowering plant species with 12 chromosomes in its egg cell?

While the endosperm is a triploid tissue formed after triple fusion. Thus, if the synergids have 8 chromosomes, the aleurone layer (part of endosperm) will have just triple of that of chromosomes in the synergids, i.e. 24 chromosomes.

Is endosperm a diploid or haploid?

Complete answer: The endosperm of the gymnosperm is a haploid tissue. In gymnosperm, there are two sperm nuclei of which one degenerates and the endosperm formed is not a real endosperm but a nutritive tissue for the growth and germination of the embryo.

What would be the number of chromosomes of the Aleurone cells of a plant with 42 chromosome in its root tip cells?

Since, the cells of aleurone layer are triploid, the number of chromosomes woud be 63 as root tip cells. (2n) has 42 chromosomes.

What would be the number of chromosomes in aleurone layer of self pollinated maize plant if megaspore mother cell has 20 chromosome?

Thus if the megaspore mother cell has 20 chromosomes then, it means that 2n = 20. From here we conclude that n = 10. In addition to this, the ploidy of the aleurone layer is 3n (triploid) as it is the result of double fertilization, this signifies that we calculate chromosomes number as, 3 × 10 = 30 chromosomes.

What would be the number of chromosomes?

In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.

How many chromosomes would you expect in the following if the diploid number of chromosomes in an angiosperm plant is 18?

54 chromosomes will be present in the Endosperm. It is the fact that the Endosperm of Angiosperms are triploid in nature i.e. 3n.

How do you calculate endosperm chromosomes?

If 3 gametes combine to form the endosperm (one sperm plus 2 polar nuclei), then the endosperm cells must contain 3 x 20 = 60 chromosomes.
