Answer:
Electricity, gravity of earth and structure of atom provide evidence.
Explanation:
The investigation of electricity, gravity of earth and structure of atom helps the student to understand that without touching, one object apply force on another object. In electric current, we can see the property of magnetism due to which it attract and repel objects while in gravity of earth, the earth apply gravitational force to attract objects towards itself. in the structure of atom, proton present in the nucleus which attract the electron present in the shells.
Answer:
the answer is option b hope you understand
Answer:
In the F1 generation
RR = 0%
Rr = 50% (or 0.5)
rr = 50% (or 0.5)
Explanation:
A pink flowering plant has the genotype Rr. It is heterozygous for the allele. The alleles for this gene appears to show incomplete dominance, as the heterozygous phenotype is a blend of the two homozygous genotypes.
A white flowering plant has the genotype rr. It is homozyogous for the white allele
A punnet square of the cross is shown.
The resulting punnet square shows that only Rr and rr genotypes are possible, at a ratio of 50:50 (or 1:1). Therefore, the genotype frequency of Rr is 50%, and rr is 50% in the F1 generation. This can also be written as 0.5. It is not possible to get a red plant, as the genotype RR can not come from this cross
Answer:
9/256
Explanation:
According to Mendel's experiments the results for the heterozygous are in the ratio 3:1
As each gene is considered separately and the multiplication rule is used. Therefore the probability of getting a solid color would be 1/4 and black fur would be 3/4. Similarly the probability of getting the colored fur is 3/4 and getting a piebald( white patches) is 1/4
Then the combined probability is (1/4*3/4*1/4*3/4)= 9/256
Answer:
0.125
Explanation:
The probability of having a daughter is 50%.
The genotype of both parents is AO. The chance of having a child with an OO genotype is therefore 0.25
The probability of having a daughter who has the OO genotype and therefore blood group O is thus 0.5 × 0.25 = 0.125.
