Answer and explanation;
-The nearly one-to-one ratio seen in the offspring suggests it is likely inherited as a dominant trait, with the dwarf parent being heterozygous for the dwarf allele along with the normal parent being homozygous for the normal allele.
-Metaphyseal chondrodysplasia, Schmid type (MCDS) is a type of skeletal disorder in which there is abnormal bone formation at the end of the long bones (metaphyses). MCDS is caused by a mutation in one of the collagen genes. The MCDS mutation is passed on in an autosomal dominant manner.
