Females have 2 X chromosomes and males have one X and Y the Punnet Square above shows the possible outcomes of their offspring
Video to watch on heredity:
male and female combine, they produce offspring
1.What are traits? What do they have to do with chromosomes?
2.How many chromosomes does the human body have?
3.Compare and contrast sexual and asexual reproduction.
4.What is one benefit of asexual reproduction?
5.What is the Theory of Inheritance? What does it have to do with the appearance of the offspring?
6. What chromosomes to males and females have? What is the chance their baby will be a boy?
