Answer:
The genotypic and phenotypic ratios of the F1 generation in a cross between heterozygous wire-haired dog with a smooth haired dog are 1 Ss: 1Ss and 1 wire haired: 1 smooth haired respectively.
Explanation:
According to this question, a gene coding for hair texture in dogs. Wire hair (S) is dominant to smooth hair (s).
If a heterozygous wire-haired dog (Ss) with a smooth haired dog (ss), the following gametes will be produced by each parent:
Ss- S and s
ss - s and s.
Using these gametes in a punnet square (see attached image), the following genotypic and phenotypic proportion of offsprings will be produced:
Ss - wire haired
Ss - wire haired
ss - smooth haired
ss - smooth haired
Your welcome!! ;)
