Mendel's Law of Segregation states that a diploid organism passes a randomly selected allele for a trait to its offspring, such that the offspring receives one allele from each parent.
Explanation:
A Male's testies includes two chromosomes which are x and y (sperms)
XX= female
XY= male
A female's ovaries also have 2 chromosomes but both are x.
Whichever sperm ( depending on the x and y) enters the eggs that's the gender of the baby. If a x sperm enters the egg first it's a girl because the girl egg already contains the x chromosome so it's a gir. If a y sperm enters the egg first then it's a boy.
I know this wasn't the question but hoped I helped you out a little bit more :)
To find the average number of cell cultured per area, you have to divide the total cell count with the total area. The cultured cells contains 7 x 10^5 cells count in 50 ml of medium area. The number would be: 7 x 10^5 cells / 50ml= 0.14x 10^5 cells /ml= 1.4 x 10^4 cells/ml
