Answer:
Mendel first observed the different patterns of gene segregation for selected traits in garden peas and was able to determine probabilities of recurrence of a trait for subsequent generations and analyses of large families with many affected individuals can be used to determine whether a disease-associated gene is located on an autosome or on a sex chromosome, and whether the related disease phenotype is dominant or recessive.

<h2>D) is the correct option </h2>
Explanation:
- Conservation tillage conserves soil by reducing erosion
- In the Midwest, erosion by water is the primary concern, whereas western regions of the country are more susceptible to wind erosion
- Soil erosion removes the productive layer of topsoil, reducing crop yields and land value
- Soil removed from fields eventually ends up as sediment in streams, rivers, or lakes
- Sediment collects in surface waters, reducing their water-holding capacity and some crop nutrients and pesticides attach to soil particles and are carried and deposited in waterways along with the soil
- Conventional tillage, such as moldboard plowing, leaves the soil surface bare and loosens soil particles, making them susceptible to the erosive forces of wind and water
- Conservation tillage practices reduce erosion by protecting the soil surface and allowing water to infiltrate instead of running off
