Answer:
Oviparous
Explanation:
The most common reproductive strategy in marine ecosystems is oviparity. 43% of cartilaginous fish are oviparous.
Virus’s are not considered living organisms because:
1. they cannot reproduce by themselves.
2. are structurally very simple.
3. can only be visualized using an electron microscope.
4. typically are associated with diseases.
We solve the problem using the Hardy-Wineberg equation.
Let us start with the homozygous recessive number of white trait,
∴ q² =
= 0.16
We have the frequency for white trait as q = 0.4
Solving for the frequency of blue trait by using the fact that,
p + q = 1
∴ p = 1 - q = 1 - 0.4 = 0.6
Now we can calculate 2pq in p² + 2pq + q², which is the frequency for heterozygous blue trait,
∴ 2pq = 2 x 0.6 x 0.4 = 0.48
And the homozygous blue trait is given by the expression,
∴ p² = 0.6² = 0.36
Hence, the carriers for the trait of blue are, 0.48 + 0.36 = 0.84, or 84% of 142.
∴ 84% of 142 = ![\frac{84 \times 142}{100} = 119](https://tex.z-dn.net/?f=%20%5Cfrac%7B84%20%5Ctimes%20142%7D%7B100%7D%20%3D%20119%20)
Answer is 119.
