Use the table to answer the question.
Plant A Plant B Plant C
tt TT Tt
The table shows the genotypes of three pea plants for the allele for height. Which prediction about the three plants is the most reasonable?
(1 point)
Responses
Plant A and Plant C will have similar heights.
Plant A and Plant C will have similar heights.
Plant C will be the shortest.
Plant C will be the shortest.
Plant B and Plant C will have similar heights.
Plant B and Plant C will have similar heights.
Plant A will be the tallest.
Plant A will be the tallest.
Based on the information in the table, the most reasonable prediction is that Plant A will be the tallest. This is because Plant A has the genotype TT, which means it has two dominant alleles for height. Plant B and Plant C both have at least one recessive allele, so it is more likely that they will have shorter heights compared to Plant A.
In rabbits, B represents the allele for black coat and b represents the allele for white coat. Black is dominant over white. If a rabbit has the genotype Bb, what is the rabbit's phenotype?

Responses
gray
gray
black
black
white
white
Speckled
If a rabbit has the genotype Bb, the rabbit's phenotype would be black. This is because the black allele (B) is dominant over the white allele (b), so even with just one copy of the black allele, the rabbit will have a black coat.
so whats the awnser??????
The answer is black.
R = red flowers
r = white flowers
According to Mendel’s law of dominance, which genotype(s) represent offspring with white flowers?
(1 point)
Responses
Rr
Rr
rr
rr
rr or Rr
rr or Rr
RR or Rr
RR or Rr
According to Mendel's law of dominance, the genotype that represents offspring with white flowers is "rr". This is because the allele for white flowers (r) is recessive, and in order for an individual to have white flowers, they must have two copies of the recessive allele.
nvironmental factors and genetics have an effect on plant growth. Evaluate each of the statements and sort them into things that increase plant growth and things that decrease plant growth.
