In the given case of cross, the probability of spotted and solid fur are:
- No, there is chance are not 100% solid fur in puppies only 50%
- The percentage of the spotted fur puppies will be - 50%
In the given case here is spotted fur "f" is the recessive allele in dogs and solid fur "F" is the dominant allele. As we know that in heterozygous condition, dominant allele masks the effect of the recessive allele, however in absence of dominant allele or two recessive alleles present than the recessive allele express its characteristic.
- The cross between => heterozygous male x spotted fur female
Ff ff
- Gametes will be: F, and f f, and f
- Then cross will be as given in Punnett square:
F f
f Ff (soild) ff (spotted)
f Ff (solid) ff (spotted)
Thus, The correct probability or percentage is -
- Percentage of solid fur => 2/4 = 50%
- Percentage of spotted fur => 2/4 = 50%
