1. Two black hamsters are mated and over time they produce 29 black and 9 white offspring. Give the genotypes of the parents and the progeny. Use the letter B for the alleles.
2. What is the purpose of mitosis and compared to meiosis. I am not asking about the different stages of each, but the purpose of each.
1.Let us assume that parents are Bb and Bb and carry out a punnet square to find out the progeny
parent2
| parent1 | B | b |
| B | BB black | Bb black |
| b | Bb black | bb white |
Black : White = 3:1 which goes rougly with 29:9
This confirms that :
Parents genotypes are : Bb and Bb
Offspring genotypes are: 1 BB , 2Bb and 1bb
2.The purpose of mitosis is to allow for growth of somatic cells and to replace the somatic cells that are worn out.
The purpose of meiosis on the other hand, is the production of sex cells or gametes i.e sperm cell and egg cell.
