There is a risk of inbreeding https://twitter.com/GaneshaRavindra/status/1199005714779267072">https://twitter.com/GaneshaRa...

For starters your family tree would look like this

This is the first generation, i.e. your grandparents

Note : blue is your grandfather& #39;s genes

Red is your grandmother& #39;s

This is the second generation representing your Bua and fufa

Note : Purple represents fufa& #39;s genes.

This is the possible cases for the third generation i.e. your bua& #39;s daughter and you.

Note: orange represents your mother& #39;s genes

See that there is a 50% chance of subject and bua& #39;s daughter to have the same gene inherited through the grandfather

Taking the case in which bua& #39;s daughter has grandfather& #39;s genes, there is a 25% chance of having an offspring that has mostly your grandfather& #39;s genes. A case of inbreeding! Although the X and Y chromosomes don& #39;t pair up so there are no chances of 2 recessive genes being +

+ homozygous, the risk is less but still there are normal chromosomes too.

Also look at the second case in this punnet square. The offspring has genes from your father& #39;s wife and bua& #39;s husband https://abs.twimg.com/emoji/v2/... draggable="false" alt="😂" title="Face with tears of joy" aria-label="Emoji: Face with tears of joy"> https://abs.twimg.com/emoji/v2/... draggable="false" alt="😂" title="Face with tears of joy" aria-label="Emoji: Face with tears of joy"> https://abs.twimg.com/emoji/v2/... draggable="false" alt="😂" title="Face with tears of joy" aria-label="Emoji: Face with tears of joy">
