Answer:
heyyy and its the coding of the cells from your parents that makes u
Explanation:
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
however the Question is not clear, but, the geosphere is defined as the natural environment we live in. it also controls the minerals distribution, soils and rocks and generate natural hazards that shape the land and impact the lives on earth.
TRUE. the placenta develops in the mother's uterus during pregnancy. The structure provides oxygen and nutrients to the growing baby and removes waste products from the babys blood
