Answer:
Purple is the dominant color in hedgehogs and yellow is recessive. Cross 2 heterozygous individuals with each other. What percentage of the offspring will carry the purple allele? one over four
Suppose that the proportion of the white crest alleles (r) is given by w and that of the Red crest allele (R) is given by p. We have that p+w=1. The probability that an individual has 2 r alleles is given by w*w since for each allele position the probability is w. Only these individuals have a White phenotype. Hence, we get that w^2=
; the right hand side is the proportion of white birds in the total population. Doing the calculations, this yields that w=0.37. From this, we calculate that p=0.63. The possible ways we have heterozygous individuals are the combinations Rr and rR. The probability for each of those is p*w. Thus, the total probability is 2pw. This is equal to 0.466=0.47. This is the fraction of the future population that is going to be heterozygous assuming the conditions of the Handy-Weinberg equilibrium like random reproductive matching etc.
D is the answer because carbondioxide and oxygen are both needed for plants or green plants to survive.

Motor coretex is essential for receiving information that you are moving your legs.
<h3>What is motor cortex?</h3>
- The motor cortex's main job is to provide signals that control how the body moves. It is anterior to the central sulcus and a portion of the frontal lobe.
- The primary motor cortex, premotor cortex, and supplementary motor area make up this region.
- The motor cortex generates signals that are particular to movements and sends them to the muscles via spinal cord circuits and motoneurons to regulate motor behavior.
- For the execution of movements to be precise, coordinated muscle activation patterns are required.
