Answer:
1/4.
Explanation:
The autosomal dominant trait means that the trait is visible in homozygous dominant and in heterozygous condition. The X linked recessive trait will be pass down from mothers to their sons and daughters will show the trait in homozygous recessive condition only.
The man is achandroplastic dwarf ( Aa) with normal vision (XY ) is married with woman that has normal height (aa) with color blind (XhXh). They have a daughter who is dwarf ( Aa). The probability of being dwarf can be calculated by the cross Aa × aa. The offspring are Aa, Aa, aa, aa. Means 1/2 are the probability of being hetterozygous for achondroplastic . The vision probability is calculated by cross XY and XhXHh. The probability that female is heterozygous is 1/2.
So, the heterozygous probability for both trait is 1/2× 1/2 = 1/4.
Answer:
Best three management practices would be: Stream side Buffers, Cover Crops, Nutrient Management Plans.
Explanation:
- Conservation and management practices must be taught to every farmers for the deduction of chemical effect and nutrition erosion activities.
- Areas bordering stream banks that are taken out of crop production or pasture use and planted with native trees, shrubs, or grasses, helps in managing the decrease in soil fertility and an increase in chemical runoff into the waterways. This technique is called as the stream side buffers.
- To reduce runoff and erosion and enrich the soil with organic matter, cover crops must be planted. These crops soaks all the excess chemical fertilizers left on the field.
