...... There are typically only 50 or so genes in mitochondria and a little over 100 in chloroplasts. There are typically 25,000 pairs of genes on the chromosomes which are usually inherited equally (one of each pair) from the pod and pollen parents.

However, there are many other factors that can affect crosses and cause the seedlings from reciprocal crosses to be different.

.........Every characteristic of a plant relies on both the chloroplast and the mitochondria. In that respect, scape height and flower size are not different. Characteristics thought of as plant habit are not different from those thought of as affecting the flower.

Less than 200 genes outside meiosis from the pod parent and 25,000 pairs equally shared by both parents involved in producing offspring. If it is 'equal', then what are the factors that effect a cross and tilt characteristics to one or the other of the parents? If it's truly equal, then it's similar to a coin toss. Completely arbitrary on whether offspring favors one parent or the other. If there are factors aside from chloroplasts and mitochondria, then those are the ones I'd like to hear information about. Fertility and variegated foliage are pretty well known as things influenced maternally. It's the other factors affecting those 25,000 pairs contributed by the parents. Where does the favoritism come into play?
