A pregnant woman asked her doctor about the chances of her baby being a boy. The doctor said that there was an equal chance of the baby being a boy or a girl. The doctors puts up the following explanation.

The sex cells of the women have only the X chromosomes present in them. Whereas the sex cells of the male have a X and Y chromosome present. The Punnett square shows the likelihood of having the gender of the child being a male (boy).

Based on the Punnett square, the chances having a boy is 50% since there are 2 XY out of the 4 genotypes.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.  

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
