Triggerfish and hawks fish. They have depressed body shape and their tail is diphycercal. Their tail shape gives them manoeuvrability and their body shape allows them to fit into small places on the reefs which makes them good for adaptations.
Shark fish; they have fusiform body shape and heterocercal tail shape and their good adaptation help them to be top predators and need speed to hunt down their animal.
Stingray; they have depressed body shape and diphycercal tail shape. Their good adaptation helps them to timid fish who feed and hide along the bottom.
Answer:
6,25%
Explanation:
Considering that the couple has a trait of sickle cell anemia, we know that both are heterozygous for the disease (Aa) and therefore can have children with the following genotypes:
Parents: Aa X Aa
Children: AA(A x A), Aa(A x a), Aa (a x A) and aa(a x a)
Knowing that sickle cell anemia only occurs in homozygous individuals, the probability for children to have the disease according to each crossing is:
A x A = 1/4 = 25%
A x a = 1/4 = 25%
a x A = 1/4 = 25%
a x a = 1/4 = 25%
The probability of forming each homozygous child (aa) is 1/4 or 25%. Since they are two children, the probability of both having sickle cell anemia is calculated by multiplying the probability of each, so:
1/4 × 1/4 = 1/16 = 0.0625 = 6.25%
It is concluded that the probability of a heterozygous couple for sickle cell anemia to have two children with the disease is 6.25%.
