What is the fertilized egg chromosome number of a cow?
30
What process union of egg and sperm restores chromosome number?
Fertilization.
Is there an X or Y chromosome in an egg?
An egg will have the X chromosome and the sperm will have an X or Y chromosome.
The chromosome number in an egg cell nucleus of a plant is 14 What is the normal chromosome number in a root epidermal cell of the same plant?
28
How many chromosomes does a egg in an onion have?
There are 8 chromosomes in an onion egg (or gamete) cell.
What is the diploid chromosome number in onion cell?
onion cells have 16 chromosomes. Which is 8 pairs
What is the fertilized egg chromosome number of a cow?
30
What is the chromosomes number of an onion root cell during anaphase?
The chromosomes number is 8 in an onion root cell during interphase.
What process union of egg and sperm restores chromosome number?
Fertilization.
Is there an X or Y chromosome in an egg?
An egg will have the X chromosome and the sperm will have an X or Y chromosome.
The chromosome number in an egg cell nucleus of a plant is 14 What is the normal chromosome number in a root epidermal cell of the same plant?
28
What is a cell with one-half the regular number of a chromosome?
A sperm cell or an egg cell.
How many chromosomes does a egg in an onion have?
There are 8 chromosomes in an onion egg (or gamete) cell.
How many chromosome in each sperm or egg has horse?
If the diploid (2N) number is 64 the haploid (1N) number is 32.
How does the alternation of meiosis and fertilization in the life cycles of sexually reproducing organisms maintain the normal chromosome count for each species?
Simple, Meiosis reduce the chromosome number in half while fertilization doubles the chromosome number. n=chromosome number Meiosis = 2n (primordial germ cells) ----> n (sperm cell/egg cell/polar bodies) Fertilization = sperm (n) + egg (n) ----> 2n (zygote)

If the chromosome number of a typical onion root tip cell is sixteen before mitosis what is the chromosome number of the each newly formed nucleus after nuclear division has taken place?
the same as before, each will have sixteen. If it was meyoses it would be 1/2 that (8) Mitotic division creates exact replicates of the original, so the answer is 16. Meosis occurs in the flower of the onion, it's sex cells ovules and pollen will have only 8 chromosomes
