These changes are likely genetic mutations
<h2>Further Explanation
</h2>
Evolution is the process of change in all life forms from one generation to the next, and evolutionary biology studies how this evolution takes place. Every generation of organisms inherits traits owned by their parents through genes. <u><em>Changes (called mutations)</em></u> in this gene will produce new traits in the offspring of an organism. In an organism's population, some traits will become more common, while others will disappear. traits that help the survival and reproduction of organisms will be more likely to accumulate in a population than unfavorable traits. This process is called natural selection. The income of more offspring than the number of parents along with the inheritance of these traits is an additional fact about life that supports the scientific basis of natural selection. In a long time, this isolated population will become a new species.

The disorder where the grandfather and the grandchild are affected is related with the X chromosome and is called Sex linked or X linked disorder.
<h3><u>Explanation:</u></h3>
All the sex linked disorders are recessive in character i.e the normal allele is dominant over the mutated allele. In females, there are 2 X chromosomes, so the mutated allele is only expressed when there are both the mutated alleles, else its masked by the dominant normal allele. But in males, there's only one X chromosome, so if a mutated allele is present, it's readily expressed.
If the Grandfather is diseased, then he must have that mutated allele in X chromosome. Through reproduction, its received by the mother, but she is normal because the other allele received from grandmother was normal. But mother has one of the X chromosomes with mutated allele, which is received by the grandson who again becomes diseased.
So the disorder must be X linked disorder
A cycadophyta is a biological dividsion, and within this,nthree are three families, and these are; Cycaclaceae, Strangeriaceae and Zamiceae. The plants of these are seed plants, which generally have characteristics, such as a stout, short and tough trunk made of wood, with a crown like span of evergreen leaves, with a cone shape protruding from the centre of the tree.
Sorry, I wasnt able to attach an image, but if you google cycadophyta, this is what they look like.
Sorry for the inconvenience, hope this helps
