With the assumption that schmid-type metaphyseal chondrodysplasia is rare, is this type of dwarfism inherited as a dominant or recessive trait and why?

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.

from the original order (top to bottom) the new order will go

1 (founder)

4 (hawk)

2 (mutate)

3 (next generation)
