Best answer: Do humans have gamete cells?

In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells. … Haploid gametes are produced during meiosis, which is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half. How many gametes cells …

Frequent question: How many genetically different gametes are possible?

Humans have 23 pairs of chromosomes. That means that one person could produce 223 different gametes. In addition, when you calculate the possible combinations that emerge from the pairing of an egg and a sperm, the result is (223)2 possible combinations. How many genetically different gametes can be made? Hence, 1×2×2=4 types of gametes would …

What is the non dividing phase of mitosis?

The G0 (G zero) phase is the phase where a cell takes a break from the cell cycle. Cells can enter and exit the cell cycle. When the cells are in ‘rest’ they are in what is called the G0 (G zero) phase . When they receive a signal to start cell division, they can …

Is anaphase 1 meiosis or mitosis?

Anaphase I is the third stage of meiosis I and follows prophase I and metaphase I. This stage is characterized by the movement of chromosomes to both poles of a meiotic cell via a microtubule network known as the spindle apparatus. This mechanism separates homologous chromosomes into two separate groups. Is anaphase in mitosis or …

What stage are chromosomes made?

During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes. Chromosomes are made of a single piece of DNA that is highly organized. In what stage are chromosomes formed? The phases of mitosis can be …

Is incomplete dominance phenotype?

Incomplete dominance is when the phenotypes of the two parents blend together to create a new phenotype for their offspring. An example is a white flower and a red flower producing pink flowers. Codominance is when the two parent phenotypes are expressed together in the offspring. Is dominant a phenotype? The genes that are expressed …

What is the exchange of genes between chromosomes called?

During this lining up, DNA sequences can be exchanged between the homologous chromosomes. This type of genetic recombination is called crossing over, and allows the daughter cells of meiosis to be genetically unique from one another. What is the exchange of chromosomes called? Chromosomes exchange genetic material during meiosis in a process called crossing over. …

What is dominance Why are some alleles dominant and some recessive?

Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked. What exactly is …
