Which Parent Determines The Gender Of The Baby

In most cases: The basic risk of a female having a ds offspring increases from a low in the early 20's (1/2000) to 1/100 @40 & 1/12 @ 49.Chromosome origination studies suggest the anomaly ares in egg rather than the sperm, likely because a blighted sperm doesn't swim as effectively.Age is therefore less an issue for the male. In rare translocation ds, gender is not as much an issue. ...Read more
Is the ramzi method of which side the placenta is on accurate in determining the gender of a baby?

Yes: Maternal contribution to the offspring is limited to her female sex chromosome. Since a pair of x's make her female, that is all she can put into an egg. A male has an x and a y chromosome, so ~half his sperm carry an x and half carry a y. At fertilization the mothers x joins dad's x or y and a girl or boy will result. ...Read more
Many things: Motor development is a complex series of gains in coordination and strength. In infants, lack of tummy-time can lead to late crawling due to weaker upper bodies.
