Question

what are the odds of a genetically typical couple having a female child? 25% 100% 0% 50% rewatch

Explanation:

In human reproduction, the sex - determining chromosomes play a role. Females have XX chromosomes and males have XY chromosomes. The male can contribute either an X or a Y chromosome, while the female always contributes an X chromosome. There are two possible combinations for the offspring's sex chromosomes: XX (female) and XY (male). Since there are two equally likely possibilities for the combination of sex - determining chromosomes during fertilization, the probability of having a female child is 50%.

Answer:

D. 50%
