I believe it is all of the above. So D.
Answer:
I honestly know its B cause I had the same question asked by my teacher
Answer:
Explanation:
a. Since both the parents are carriers, they have one allele that is the gene for the normal trait and one gene that is for the sickle cell trait. So the genotypes of the parents are Hh
b. If we use a punnett square:
H h
H HH Hh
h Hh hh
Genotypic ratio: 1 HH: 2Hh: 1hh
Phenotypic ratio: 1 normal blood cell: 2 sickle cell carriers: 1 sickle cell disease
These factors are essential for the growth and life span of the population of species in an ecosystem. The larger the space, the more light it obtains, and the more food the area produces; the larger the population of species in an ecosystem. having less space, light, and food, the results would be vice versa.
