JordanHeritable characteristics are passed on from parents to offspring through genes. Genes are segments of DNA that code for specific traits, and they are inherited through the reproductive cells (sperm and egg). Offspring inherit a combination of genes from both parents, which determines their unique genetic makeup and characteristics.

How many new heritable mutations are estimated to occur in each human child?
1-2
What traits of cattle are the most heritable?
Milk production, growth rate, and carcass quality traits such as marbling and muscling are typically among the most heritable traits in cattle. Generally, traits that are more easily measured and observable tend to be more heritable.
Do all mutations result in heritable changes?
yes, only heritable changes in the DNA come under the perview of mutation.
When individual select mates based on heritable traits?
This is known as assortative mating, where individuals choose partners based on specific traits that are heritable. This can lead to the reinforcement of those traits within a population over generations.
What conditions must be met in order for selection to occur?
Selection occurs when there is variation in a population, that variation is heritable, and individuals with certain traits have a higher chance of survival and reproduction. This process allows advantageous traits to become more common in a population over generations.
