50% het?

[CH2O2]

parent one has one recessive allele and one normal allele
parent two has one recessive allele and one normal allele
egg #1 has 4 possibilities
1. to receive both recessive alleles
2. to receive recessive allele from parent one and normal allele from parent two
3. to receive normal allele from parent one and recessive allele from parent two
4. both normal alleles

If the egg gets both recessive alleles it is easily identified.
If the egg gets only 1 recessive allele or both normal alleles, they cannot be distinguished form each other.
you have 3 options
1. to receive recessive allele from parent one and normal allele from parent two
2. to receive normal allele from parent one and recessive allele from parent two
3. both normal alleles

so the chance of the egg getting a recessive allele is 2/3 or 66%
repeat the above for each other egg in the clutch.

Now i understand. Thanks
