Document Summary
Hh and hh are the genotypes that will give you huntington disease. 50% chance of child having huntington with an hh x hh cross. Marissa and daniel want to start a family. Marissa is healthy, but her mom had scd. The chance of having a healthy child 50% Darwin: variation is due to the nature of the organism and the nature of the conditions. Genes can give you your potential height, but you can change that by having a good/bad diet. Variance: a measure of how much variability there is in the population. (more different phenotypes) A parent and child share 50% of their genes. Measures % of phenotype due to genes for a certain population at a certain time. Be carefulonly for this population at this. Issue with using relatives (mom dad sister brother) is that they probably share the same environment, so it doesn"t quite separate the environments. So, try to separate genetic influences from environment.
