Genes are found on tiny spaghetti-like structures called chromosomes (say: KRO-moh-somes). And chromosomes are found inside cells.

Q. How many chromosomes are in the parent first cell?
Germ cells contain a complete set of 46 chromosomes (23 maternal chromosomes and 23 paternal chromosomes). By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell.
Q. How many chromosomes are in the parent and daughter cells?
During Interphase, the DNA is copied. Hence, there are 2 copies of one chromosome. This means that there are now 46 pairs of chromosome in the parent cell. However, during cytokinesis, the cell divides itself into two, meaning that each daughter cell are left with 23 pairs of chromosomes or 46 chromosomes.
Q. How many chromosomes are in a human parent cell?
46 chromosomes
Q. Who is the father of gene?
Gregor Mendel
Q. What’s the difference between genes and DNA?
DNA is the genetic material, which is involved in carrying the hereditary information, replication process, mutations, and also in the equal distribution of DNA during the cell division. Genes are the DNA stretches which encode for specific proteins.
Q. Do sisters have same DNA?
Because of recombination, siblings only share about 50 percent of the same DNA, on average, Dennis says. So while biological siblings have the same family tree, their genetic code might be different in at least one of the areas looked at in a given test. That’s true even for fraternal twins.
Q. Do mixed race babies have better genes?
It’s good to be mixed-up. People whose parents are distantly related are, on average, taller, smarter and better educated than those whose parents are close relatives. Based on what we know about plants and animals, biologists have long suspected that people of mixed parentage have a genetic advantage.
Q. Is it good to have mixed babies?
Research has shown that children with a true multiracial or multicultural identity generally grow up to be happier than multiracial children who grow up with a “single-race” identity. Multiracial children in divorced families may have greater difficulties accepting and valuing the cultures of both parents.
Q. Are interracial babies healthier?
Biracial children may have poorer health relative to single-race children because higher shares of biracial children are born to cohabiting parents and children born to cohabiting parents have greater exposure to family instability than those born to married parents.
