A carrier of a genetic disorder who does not show symptoms is most likely to be heterozygous for the trait and able to transmit it to offspring. This particular individual has inherited a recessive allele for a genetic trait or mutation but does not display that trait or show symptoms of the disease. They are referred to as genetic carriers. The chance of two carriers having an offspring with the disease or genetic disorder is 25%
I think it’s DNA molecule
1. Mitosis takes place within somatic cells (cells that make up the body). Meiosis takes place within gamete cells (sex cells).
2. One single division of the mother cell results in two daughter cells. Two divisions of the mother cell result in four meiotic products or haploid gametes.
3. A mitotic mother cell can either be haploid or diploid. A meiotic mother cell is always diploid.
4. The number of chromosomes per nucleus remains the same after division. The meiotic products contain a haploid (n) number of chromosomes in contrast to the (2nd) number of chromosomes in the mother cell.
5. It is preceded by an S-phase in which the amount of DNA is duplicated. In meiosis, only meiosis I is preceded by an S-phase.
6. In mitosis, there is no pairing of homologous chromosomes. During prophase I, complete pairing of all homologous chromosomes takes place.
7. There is no exchange of DNA (crossing-over) between chromosomes. There is at least one crossing-over or DNA exchange per homologous pair of chromosomes.
8. The centromeres split during anaphase. The centromeres do separate during anaphase II, but not during anaphase I.
9. The genotype of the daughter cells is identical to that of the mother cells. Meiotic products differ in their genotype from the mother cell.
10. After mitosis, each daughter cell has exactly same DNA strands. After meiosis, each daughter cell has only half of the DNA strands
Mass is the amount of matter in an object. Move to a different planet and an object's weight will change, but its mass will be the same. There are a couple of ways to measure mass. The most common method is to use a balance.
- Balances and Scales.
- Space Linear Acceleration Mass
- Measurement Device
- Measurement Transducer
- Vibrating Tube Mass Sensor
- Gravitational Interaction
