Question
students studied mendels laws of segregation and independent assortment. they created a punnett square to show a cross between a homozygous furred mouse (ff) and a homozygous furless mouse (ff). the students then created a punnett square for a cross between two heterozygous f1 mice.
ff × ff
| f | f | |
| - | - | |
| f | ff | ff |
| f | ff | ff |
f1 generation
ff × ff
| f | f | |
| - | - | |
| f | ff | ff |
| f | ff | ff |
f2 generation
which question could be answered using the information from the punnett squares?
how many mice will be produced in the f1 generation?
will fewer furless mice survive to adulthood than furred mice?
can furred mice produce furless mice?
are furred mice the best organism to use for this investigation?
The Punnett squares show genetic crosses. They can predict the genotypes of offspring. From the F2 - generation Punnett square (Ff x Ff), we see that furred mice (FF or Ff) can produce furless mice (ff) when they are heterozygous. The squares don't provide information about the number of offspring, survival rates, or the suitability of the organism for the investigation.
