Question

In dogs, the allele for long fur (L) is dominant and the allele for short fur (l) is recessive. Cross a homozygous dominant dog with a dog with short fur. Use a Punnett square to answer the following questions, and REMEMBER TO WRITE THE PARENTAL GENOTYPE.
1. What percentage of the offspring is heterozygous?
2. What percentage of the offspring is homozygous dominant?
3. What percentage of the population is homozygous recessive?
4. What is the phenotype of the offspring? (in percentages)

Answer 1

Answer:

1. percentage of the offspring is heterozygous is 50%

2. homozygous dominant is 25%

3. homozygous recessive is 25%

4. phenotype- 1:2:1(25%:50%:25%)
