Direction: Solve the problem using a Punnett square. In fruit flies, humans and other mammals, sex is determined by an X-Y system However, many organisms do not have the X Y system of sex determination. For example, birds have a Z - W system Male birds are ZZ whereas females are ZW. In chickens, barred feathers (Z) are dominant over nonbarred feathers (Zb). a. Draw a Punnett square that shows the results of a cross between a barred female and a nonbarred male. b. What is the probability that the offspring will be: i. Barred females? ii. Nonbarred females? iii. Barred males? iv. Nonbarred males?

Sexual Motivation

Sexual motivation refers to a person's overall desire for sexual activity. It is an unusual motivation. Generally, among lower animals, the term 'drive' is commonly referred to as sexual motivation. It means a certain internal force drags the animal to be involved in reproductive behavior. On the contrary, humans are not simply driven by any internal force; rather, the sexual motivation in humans is due to several factors such as biological (hormones, genes), environmental (familial upbringing, chemical exposure) and physiological factors (culture, desire) which further determine engagement in sexual activities.
