How many chromosomes does a human gamete (egg or sperm cell) have? A) 46. B) 23. C) 2. D) 13. E) 92. In humans, each cell normally contains 23 pairs of chromosomes. How many chromosomes does a human cell contain? How many chromosomes are in a normal human cell a...
How many sex chromosomes are present in a human body cell? How many chromosomes does each human gamete contain? a) 92 b) 46 c) 16 d) 23 If humans have 46 chromosomes in each of their body cells, how many chromosomes would you expect to find in a sperm cell?
For the fruit fly, the diploid number is8, which can be written as 2N = 8, where N represents twice the number of chromosomes in a sperm or egg cell. Some cells contain only a single set of chromosomes, and therefore a single set of genes. How many chromosomes are there in fruit fly?
Dogs have 39 pairs, and some plants have as many as 100. Chromosomes come in pairs. Each chromosome is a tightly packed strand of DNA. There are two strands of DNA joined together at the centromere to form an X-shaped structure. One strand comes from the mother and one from the father...

The human chromosomes hold the DNA of the human genome. Each parent contributes 23 chromosomes. Bacteria reproduce asexually. This means that, when a bacteria cell splits, both halves of the split are identical -- they contain exactly the same DNA. The offspring is a clone of the parent. ...
Girls and women typically havetwo X chromosomes(46,XX karyotype), while boys and men typically have one X chromosome and one Y chromosome (46,XY karyotype ). What are haploids and diploids? Diploid describes a cell that contain two copies of each chromosome. Nearly all the cells in the ...
Each parent contributes 23 chromosomes. Bacteria reproduce asexually. This means that, when a bacteria cell splits, both halves of the split are identical -- they contain exactly the same DNA. The offspring is a clone of the parent. As explained in How Human Reproduction Works, higher ...
(the effect of relaxing this assumption is explored in Additional file1: Note 17) but the Y:X ratio of its gametes will be 1:1 − ewhereeis the probability of successful cleavage (and hence the fraction of X chromosomes destroyed). The modified Y can thus expect to be present in...
How many chromosomes does each human gamete contain? a) 92 b) 46 c) 16 d) 23 The human germ cell line (23 pares of homologous chromosomes) allows for how many combinations of maternal and paternal chromosomes every time a gamete is produced? a. 9:23 b. 223 c. 3,...
