Studies conducted in England during the Industrial Revolution have shown that children born to poor families were, on average, shorter than those born to wealthier parents. The most likely explanation for this difference in height is a difference in

Spores grow into a plant called a gametophyte. A gametophyte produces gametes, or eggs and sperm. Gametes fuse to make a fertilized egg, or zygote. The zygote grows into a sporophyte, which produces spores and start a new cycle all over again.
17. The genotype of a daughter must be XHXH. Because she inherits one X chromosome from her mother and another from her father, each parent must have an X chromosome with the mutated gene. Since the father has only one X chromosome, his genotype must be XHY. The sun, who does not have the disease, has the genotype XHY. Since his father passed him the The genotype of a daughter must be XHXH. Because she inherits one X chromosome from her mother and another from her father, each parent must have an X chromosome with the mutated gene. Since the father has only one X chromosome, his genotype must be XHY. The son, who does not have the disease, has a genotype XHY. Since his father passed him the X Y chromosome, his mother must have allele that is not mutated. Therefore the mothers genotype must be XHXH.
18. Internal fertilization occurs inside the female’s body. X ternal fertilization occurs outside the female’s body. The advantage of X ternal fertilization is that many eggs can be fertilized at the same time, possibly resulting in more offspring’s. However gametes May also be washed away during external fertilization, resulting in few were fertilized eggs. Predators May also eat gametes before they can develop. A disadvantage of internal fertilization is that fewer eggs can be fertilized and offsprings generally require more time to develop.
