Triploidy refers to a condition where an individual has 1.5 times the normal number of chromosomes. Egg and sperm cells are haploid (have n number of chromosomes). Normal cells are diploid (have 2n number of chromosomes). The exact cause of triploidy in humans is not known. It may be caused when more than one sperm fertilize a single egg. Triploidy may be preferred and cultivated in plants in order to increase productivity.

What happens when 3 sperms fertilse one egg?
When multiple sperm fertilize one egg, it results in an abnormal number of chromosomes, which can lead to a nonviable embryo. This phenomenon is known as triploidy and is generally not compatible with life.
Explain the difference between trisomy and triploidy describe a way that each condition could occur?
Trisomy is the presence of an additional chromosome, such as having three copies of a particular chromosome instead of the usual two. This can occur during cell division errors, leading to an extra chromosome being introduced. Triploidy, on the other hand, is having three complete sets of chromosomes instead of the usual two. This can occur when an egg is fertilized by two sperm or due to errors in cell division during early embryo development.
What happens if two sperms enter the egg during fertilization?
When two sperms enter the egg during fertilization, it results in an abnormal number of chromosomes in the embryo, leading to a condition called triploidy. This usually results in a nonviable pregnancy and early miscarriage.
What does dispermy result in?
Dispermy is a type of polyspermy that occurs when two sperm fertilize one egg. This results in an embryo with triploid (3n) chromosomes, which is typically non-viable and leads to developmental abnormalities or pregnancy loss.
What is the maximum number of chromosomes ever observed in a human individual?
Oh, dude, the maximum number of chromosomes ever observed in a human individual is 92. Yeah, that's like double the usual 46. It's a rare condition called tetrasomy, but hey, more chromosomes, more fun, right?
What if child has 3 sets of chromosomes?
If a child has three sets of chromosomes, it is known as triploidy. This condition occurs when an egg is fertilized by two sperm, resulting in an extra set of chromosomes. Triploidy is usually not compatible with life, and pregnancies often result in miscarriage. If a baby is born with triploidy, they will typically have severe physical and intellectual disabilities.
What is a karyotpe able to identify?
Karyotypes are able to tell if there are any chromosome conditions present. These condition include Down syndrome, Turner syndrome, Klinefelter syndrome, and Triploidy.

Is a hibiscus plant a seedless plant..why?
Althouh hibiscus is a flowering plant, it rarely forms seed due genetic dis-order. Triploidy provides good number of attractive flowers but viable gametes are lacking due to lack of pairing of homologous chromosomes during meiosis.
What is the maximum number of chromosomes ever observed in a human individual?

Triploid organisms have copies of each chromosome?
In triploid organisms, there are three sets of chromosomes in each cell. This can lead to genetic imbalances and affect the organism's development and viability. Triploidy commonly occurs in plants, but can also occur in animals, including humans.
What happens when an individual has an odd number of chromosome sets eg triploidy?
Most odd chromosome pregnancies do not go full term, or the babies do not survive long after birth. However, some babies do survive. There are often times that the extra chromosome has no effect, but other times it shows itself with conditions such as Down Syndrome.
How many sets of chromsome are there in a triploid?
A triploid organism has three sets of chromosomes, which is denoted as 3n. This means that for each chromosome type, there are three copies instead of the usual two found in diploid organisms (2n). Triploidy can occur naturally or be induced artificially and is often seen in certain plants and some animal species.
