How many sex chromosomes does a sperm cell have? A triploid cell in humans would have how many chromosomes? If a human gamete possessing one extra chromosome participates in fertilization with a normal human gamete, what will be the result? How many chromosomes will the zygote have?
How many chromosomes do monkeys have? How many chromosomes are in a plant cell? What is the diploid number of chromosomes in humans? How many chromosomes are in a heart cell? How many chromosomes do bonobos have? How many chromosomes are in a zygote?
A chromosomally normal zygote has 23 pairs of chromosomes. At the time of fertilization, it has only one cell (made when the sperm cell combines with the egg cell). "The genetic information in these cells then causes the zygote to start dividing," says Dr. Richlin. Essentially, the single...
A cell has 24 chromosomes. After meisos is completed, how many chromosomes will be in a single cell? How many alleles does a person have? The typical human cell contains how many chromosomes? Explore our homework questions and answers library Search Browse Browse by subject...
After fertilization of the egg cell with the sperm, and the fusion of their nuclei, the genetic complement is restored. The the fertilised egg now having 46 chromosomes. The resulting cell is now called thezygote. The fertilization of the human egg cell with spermatozoa ...
and contains genes orthologous to those on the sex chromosome ofSchistosoma mansoni(Supplementary Tables9and10, andSupplementary Information), which is the only known Platyhelminthes species with differentiated sex chromosomes39. These observations collectively led us to propose that chromosome 1 ofS. me...
A condition in which a cell or organism contains more than the usual complement of chromosomes type of the species, by some multiple of two. Polyploidization often results from the so-called endoduplication, in which the customary doubling ofchromosome numberduring mitosis is retained in a single...
Alternatively, because early arrested zygotes and very young sporophytes likely remained unsampled in our study, it can be hypothesized that intergametophytic selfing occurs with a significant frequency in the population but its presence is masked by the process of embryo abortion at an early ...
In humans, each cell normally contains 23 pairs of chromosomes. How many chromosomes does a human cell contain? How many chromosomes are in a human zygote? If a cell has 20 centromeres, how many chromosomes does it have? If humans have 46 chromosomes in each of their body cells, det...
