The inheritance of sickle cell anemia involves incomplete dominance. (s determines normal hemoglobin, it is dominant; s is the sickle cell gene). a homozygous recessive person has sickle cell anemia. a heterozygous person has the sickle cell trait. if parental genotypes are ss and ss , what is the probability of offspring having the sickle cell trait?

Answer probability of 1.

All will be heterozygous for the traits.

Ss Ss Ss Ss

Explanation: the offspring will inherit one dominant gene from each of the parent with dominant allele SS and one recessive allele ss to be heterogeneous for sickle cell trait.

Since all is Ss Ss Ss Ss,then the.factor is 4/4=1

This follows Mendelian monohybrid inheritance rule.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
