How many chromosomes are in a butterfly egg cell?

How many chromosomes are in a butterfly egg cell?

3 chromosomes
12. If an intestinal cell in a butterfly contains 24 chromosomes, a butterfly egg cell would contain A. 3 chromosomes.

How many chromosomes do female egg have?

Human oocytes pack the mother’s DNA into 46 chromosomes. When they divide into eggs — a process called meiosis — these 46 chromosomes gather along the midline of the oocyte and are pulled in two directions by spindle fibers. The final product of meiosis is an egg cell with 23 chromosomes.

How many chromosomes do egg cells contain?

23 chromosomes
In humans, the reduction division results in two sperm cells each with 23 chromosomes or an egg cell with 23 chromosomes and one discarded polar body. The second division – or meiosis II – is called equational division.

How many chromosome do butterflies have?

This DNA is found in our chromosomes. Today, we are going to learn more about these cool chromosomes! Every species has a certain number of chromosomes: female jack jumper ants have only 2, a fruit fly has 8, humans have 46, and atlas blue butterflies have around 450!

Can a woman have Y chromosome?

Each person normally has one pair of sex chromosomes in each cell. The Y chromosome is present in males, who have one X and one Y chromosome, while females have two X chromosomes.

Does female egg have chromosomes?

Females have two X chromosomes in their cells, while males have X and Y chromosomes in their cells. Egg cells contain an X chromosome, while sperm cells contain an X or a Y chromosome.

How many chromosomes make a baby?

Genes are passed from parents to children. Each person has 23 pairs of chromosomes, or 46 in all. For each pair, you get one chromosome from your mother and one chromosome from your father. About 1 in 150 babies is born with a chromosomal condition.

How many chromosomes does a butterfly egg contain?

Q. If an intestinal cell in a butterfly contains 24 chromosomes, a butterfly egg would contain ____ chromosomes. Q. Body cells of fruit flies contain 8 chromosomes. Scientists used studies of flies to discover how egg and sperm are formed.

How many X chromosomes does a female have?

Females will have two X chromosomes within their reproductive cells, while men have one X and one Y chromosome. These can determine the sex of the offspring. For example, the women’s cell is always going to copy an X chromosome as that is all that her reproductive cells have to offer.

How many chromosomes does a male shark have?

Body cell of offspring flies have 16 chromosomes. Sperm cells have 8 chromosomes. Egg cells have 4 chromosomes. Body cells of offspring have 4 chromosomes. Q. A male shark has 40 chromosomes in each of its sex cells.

Where do the chromosomes come from in a fertilized egg?

• 23 come from the sperm, while the other 23 come from the egg. A fertilized egg (also known as a zygote), contains 23 pairs of chromosomes for a total of 46 chromosomes in the zygote. These chromosomes come from the mother via the unfertilized egg, and from the father via the sperm cell.

If a somatic cell in a butterfly contains 24 chromosomes, a butterfly egg would contain Q. A male shark has 40 chromosomes in each of its sex cells. How many would be present in its body cells?

How many chromosomes are in an egg and sperm?

One thing you need to remember about counting chromosomes is that you can count them in 2 different ways to get 2 different numbers – if you count the chromosomes in eggs or sperm, humans have 23 chromosomes. That’s called the ‘haploid’ number. But after the egg and the sperm get together, there are 46 chromosomes, which is 23 pairs.
