A fertilized egg embeds itself on the uterine wall and as cell division occurs, it will grow from an embryo to a fetus.Answer and Explanation: There is ONE sex chromosome in an egg or a sperm. Gametes (sex cells egg or sperm) are haploid cells and contain one copy of 23 chromosome...
Your genes come from your parents,and they decide everything about you such as your hair color,your eye color,your weight,your height,and so on.Genes are still a bit of a mystery(神秘) to scientists,but they' re learning new things about them all the time. ...
How many genes are on each chromosome in each cell of the human body? How many chromosomes in a human somatic cell during G2? How many chromosomes will be found in each cell during prophase? The typical human cell contains how many chromosomes?
How many genes does the Human Genome contain? The Human Genome Project has revealed that there are probably about 20,000-25,000 'haploid' protein coding genes. The completed human sequence can now identify their locations. But only about 1.5% of the genome codes for proteins, while the rest...

D.Genes are from children to parents. 2. which part tells you how scientists can tell if someone has a special gene? A.How much do genes affect athletic ability? B.How many genes play a role in sports talent? C.Are there special genes that determine fitness?
small things called "genes"(基因) in our body.In 1953,two scientists,Watson and Crick,found out that those small parts are really messages.They're written in the DNA with a special language.In 1961,another two scientists found the first "word" that they could understand in that language....

If there are k functional genes in a gene family, the equilibrium number of processed pseudogenes is k(v/delta), and the percentage of functional genes in the gene family at equilibrium is 1/[1 + (v/delta)]. v/delta values estimated for five gene families ranged from 1.7 to 15. This...
How many DNA strands are in a cell? DNA in Human Cells DNA, deoxyribonucleic acid, is the mechanism used by all living organisms to transfer information from one generation to the next. The DNA in a cell also contains all the instructions on how to build the organism it belongs to. ...
