Answer:
C. antigen-antibody reactions
Explanation:
human blood group is determined by the presence of antigens on the red blood cells which are specific proteins.
so specific antibodies are used against these antigens to determine the type of blood group after the reaction.
One reason is if someone is injured and needed to use pain pills, sometimes they get addicted to it
Hey there! :)
To solve a Punnett square, we need to master the fields in the attached picture
In the question, the given keys are:
Dominant allele Y → yellow
Recessive allele y → green
Y | y Y | YY Yy Y | YY YyThis would be the Punnett square for this question
Percentage of offspring to have yellow seeds?
Yellow is Y, then we should count which alleles had YY as a genotype?
YY = 2 out of 4, then
50%
Answer:
See the answer below
Explanation:
a) Since the pink phenotype is heterozygous, the genotype would be RW.
b) The pink genotype is RW. Hence, a cross between two pink snapdragons will go thus:
RW x RW
RR RW RW WW
<u>Expected genotypes:</u> 1/4 RR, 1/2 RW, 1/4 WW
<u>Expected phenotypes:</u> 1/4 red-flowered plants, 1/2 pink-flowered plant, 1/4 white-flowered plant.
