Answer 6

recessive. If the mother has the disease and it's recessive, then she needs to have two copies of it. That means that the child will be sure to get one copy of the disease gene from her.that means that the child will get a normal gene from the father. Since there's no combination that could wind up giving the child two copies of the disease gene, and the trait is recessive, the child can't inherit the disease.
(this was for your question with the couple)

Answer 7

(19): Internal fertilization: the egg is fertilized inside the mother
External fertilization: the egg is fertilized outside the mother.
advantages of external:1. Little amount of energy required to mate
2. Lots of offspring
3. Offspring can be spread in the environment without competition
advantages of internal:1. Embryo- protected
2. Offspring are more likely to survive
disadvantages of external:1. Many gametes won't survive
2. Many eggs aren't fertilized
3. Offspring aren't protected and may die
disadvantages of internal:1. More energy required to find mate
2. Less zygotes- less offspring
3. More energy required to raise offspring
