How many chromosome does the male gamete of butterfly have?
Male gamete of butterfly will have 190 chromosomes. Meiocytes of are butterfly are diploid i.e. 2n number while male gametes of butterfly are haploid i.e. n number.
How many chromosomes does a butterfly have?
Somebody wrote a book called “DNA and Heredity” that says butterflies have 380 chromosomes. 4. I found the best article yet in Nature magazine, which is a very famous science magazine. It says that there’s one group of butterflies where the numbers of chromosomes in different species vary from 20 to 268.
What is the chromosome number of a gamete of man?
In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells. The number of chromosomes in a single set is represented as n, which is also called the haploid number. In humans, n = 23.
What is the haploid number of chromosomes in Butterfly?
The blue butterfly species Polyommatus (Plebicula) atlanticus (Elwes, 1906) (Lepidoptera, Lycaenidae) is known to have a very high haploid number of chromosomes (n= circa 223).
What is chromosome number in Meiocyte of Apple and butterfly?
The chromosome number in meiocyte is 34.
How many diploid cells do butterflies have?
In metazoan animals, the greatest range of within-genus karyotype variation not related to polyploidy is found in Agrodiaetus blue butterflies, where diploid chromosome number ranges between species from 2n = 20 to 2n = 268 in spite of morphological similarity and very recent time of species divergence .
How many genes do butterflies have?
We present the draft 273 Mb genome of the migratory monarch butterfly (Danaus plexippus) and a set of 16, 866 protein-coding genes.
What animal has 46 pairs of chromosomes?
List of organisms by chromosome count
|Organism (Scientific name)||Chromosome number|
|Human (Homo sapiens)||46|
|Nilgai (Boselaphus tragocamelus)||46|
|Water buffalo (swamp type) (Bubalus bubalis)||48|
Why do gametes only have 23 chromosomes?
Gametes are produced by a special type of cell division known as meiosis. Meiosis contains two rounds of cell division without DNA replication in between. This process reduces the number of chromosomes by half. … Therefore, gametes have only 23 chromosomes, not 23 pairs.
Which is the male gamete?
In the human reproductive process, two kinds of sex cells, or gametes (GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female’s reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat).
Do gametes determine gender?
Sperm cells carry either an X or Y sex chromosome. Female gametes, or eggs, however, contain only the X sex chromosome and are homogametic. The sperm cell determines the sex of an individual in this case. If a sperm cell containing an X chromosome fertilizes an egg, the resulting zygote will be XX, or female.
Are gametes haploid or diploid?
Gametes are haploid cells, and each cell carries only one copy of each chromosome. These reproductive cells are produced through a type of cell division called meiosis.
What type of chromosomes are always present in gametes?
In sexually reproducing organisms, the number of chromosomes in the body (somatic) cells typically is diploid (2n; a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes. The haploid number is produced during meiosis.
How many chromosomes does each animal have?
Chromosomes are found in pairs within the cell. Each cell contains two separate copies of each gene (alleles). While a human has 46 chromosomes (23 pairs), a cat has 38 chromosomes (19 pairs) and a dog has 78 chromosomes (39 pairs).
