Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
100% of offspring will be affected. The father is affected and is homozygous dominant, the mother is unaffected and is homozygous recessive. Since there are homzygous dominant genes present, they will always be there to cover the recessive genes, therefore, all offspring will be affected. Hope this helps! (:
