Alfred Wegnar was the person who did i just took a test about that
in earth science
Answer:
The correct answer would be 25 percent.
It is the case when both the parents are heterozygous for the trait that is, both are Rr in genotype.
Thus, both the parents would produce two types of gametes one of which contain R and the other one would contain r.
The cross would result in the production of the offspring with three types of genotypes; RR, Rr, and rr.
The three genotypes would be present in the ration 1 (RR): 2 (Rr): 1 (rr).
Thus, only one out of four would be Rh- in phenotype. Hence, only 25 percent is the probability that the offspring would not be able to receive blood from either parent.
D. It would be 30 C cooler, makes the most sense because greenhouse gasses cause warmth and without them it would get colder.
