Loss-of-function mutations
do indeed cause a gene to lose some or all of its normal function. There are two different
types of these mutations:
Hypomorphic mutations are those that have lost only some of their function.
Null mutations have lost all of their function.
Loss-of-function mutations are recessive if the normal allele is haplosufficient (a single
copy is sufficient to produce the wild-type phenotype in the heterozygous genotype).
Incomplete Dominance
If true-breeding black and white mice are crossed and the offspring are all gray, this
would be indicative of what inheritance pattern?
Multiple alleles and codominance
ABO blood groups are an example of:
Yes, if each parent carries one i allele.
Could an individual of blood type O genotype have been one of the possible offspring of
parents, one of which was blood type A and the other of which was blood type B?
Incomplete dominance.
A white splashed Bl/Bl Andalausian chicken is mated with a black bl/bl Andalusian
chicken. The offspring are heterozygotes that are blue, an phenotype that is
intermediate between white and black. Which type(s) of inheritance does this illustrate?
Codominance
