dadero y justifica las falsas.
1-Los sistemas ABO y Rh están determinados genéticamente y se basan en respuesta asntígeno-anticuerpo.


2- En el sistema ABO la presencia o ausencia de los antígenos A y B en la superficie de los glóbulos rojos determina el grupo sanguíneo.


3- Los individuos cuyos glóbulos rojos poseen antígenos Rh se clasifican como Rh positivos mientras que los que carecen de antígenos Rh se clasifican como negativos.


4- La eritroblastosis fetal puede producirse cuando una madre Rh negativo está embarazada con un feto Rh positivo.

In peas, the allele for yellow seeds (Y) is dominant to the allele for green seeds (y). What would be the genotype and phenotype
grin007 [14]
<h2>The correct answer is explained below:</h2>

Explanation:

  • The allele for yellow seeds is Y.
  • The allele for green seeds is y.
  • The yellow colour phenotype is dominant over the green color phenotype.
  • The genotype of the parent who is heterozygous is : Yy.
  • The gametes produced by the parent who is heterozygous are: Y and y.
  • The genotype of the parent who is homozygous recessive is: yy.
  • The gamete produced by the parent who is homozygous recessive is: y.
  • Crossing the above parents we get the following offspring,

                                           Y                    y

                               y         Yy                  yy

               Phenotype      Yellow          Green

  • The genotype and the phenotype of the possible offspring is represent in the Punnett square above.
  • The ratio of the genotype is Yy : yy = 1 : 1.
  • The ratio of the phenotype is Yellow : Green = 1 : 1.

List 4 techniques, other than thorough cooking, that are important in preventing foodborne illness.
frozen [14]
Foodborne illness is caused by pathogenic microorganisms present in spoiled food. Apart from thorough cooking, cooked food needs to be always separated from the raw food. This keeps microorganisms present in the uncooked raw food away from the food that is ready to be eaten. In addition, our hands and areas coming in contact with the food need to be clean and sanitized. Also, food should be kept in the right and safe temperature. Finally, clean water and safe raw materials should be used for preparing meals.
