New study finds the egg may actually ‘choose’ the Sperm

RAEL’S COMMENT:
It’s always the women who choose…

 

If you’ve attended high school, you can probably remember filling in a Punnett square during a biology class. It was the simple diagram that could not only make you feel like a knowledgeable budding geneticist, but could also help you figure out the probability of your kids having blue eyes in the case the cute classmate you had a crush on agreed to live with you happily ever after.

The Punnett Square is a visual representation of Gregor Mendel’s laws of inheritance. They are three and they posit that 1) alternative forms of a gene (allele pairs) separate randomly during the production of an egg or sperm (gametes), so that each gamete only carries one form of the gene; 2) each pair of alleles segregates independently of other pairs during the formation of an egg or sperm; 3) the genotype of an individual is made of many alleles (after a random pairing of an egg and a sperm, each of which carries a random form of the gene), and the phenotype of an individual (the visible expression of the genotype) is determined by the dominant alleles and the environment.
