What is an example of a haploid genotype in organisms?
An example of a haploid genotype in organisms is the gametes, such as sperm and egg cells, which contain only one set of chromosomes.
Why is somatic recombination necessary for the development and function of both B-cells and T-cells in the immune system?
Somatic recombination is necessary for B-cells and T-cells in the immune system because it allows for the generation of a diverse range of antigen receptors. This diversity is crucial for recognizing and responding to a wide variety of pathogens, ensuring an effective immune response.
What are the possible DNA combinations that can result from genetic recombination during meiosis?
During genetic recombination in meiosis, the possible DNA combinations that can result are a mix of genetic material from the two parent cells, leading to new combinations of alleles and variations in the offspring's DNA.
Binary fission differs from mitosis because the new cells?
produced in binary fission are genetically identical clones of the parent cell, while in mitosis, the new cells have the same number of chromosomes as the parent cell but are not always genetically identical due to crossing over and other genetic recombination events.
Is it possible to have blood group B plus and genotype AA?
No, blood group B positive indicates the presence of the B antigen on red blood cells, while genotype AA suggests the presence of two A alleles. Blood groups and genotypes are inherited independently, so having a blood group B positive with genotype AA is not possible.
Genetic recombination generates diversity in what part of the immune system?
Genetic recombination is a major factor contributing to cell-mediated immunity. Different B cells and T cells are able to recognize a wide variety of targets because of the genetic recombination they undergo in developmental stages.
If all of the sex cells of an organism have the t allele the genotype of that organism must be?
The genotype of the organism must be tt, because sex cells (gametes) only carry one allele each. When gametes carrying the same allele combine during fertilization, the resulting genotype is homozygous for that allele. In this case, if all sex cells have the t allele, the organism's genotype is tt.
The genotype of the person with normal red blood cells is?
The genotype of a person with normal red blood cells is usually AA, where both copies of the beta-globin gene are normal. This results in the production of normal hemoglobin and red blood cells.

What genetic recombination in meiosis results in daughter cells D-------- from each other and from the parent cell?
Different
It is generally agreed that hormones?
Alter the enzyme activity in cells.
Will cells with mutations always make normal proteins?
Cells with mutations may not always produce normal proteins. Mutations can alter the DNA sequence, which may result in changes to the structure or function of the protein produced. These changes can lead to abnormal protein function, which can impact cellular processes and potentially contribute to disease.
What is the blood type of a woman with the genotype IA at the ABO locus?
The woman would have blood type A. A genotype of IA indicates the presence of the A antigen on red blood cells.
Is the way an organism looks and behaves a result of its genotype?
Yes, phenotype refers to the observed expressed trait while genotype refers to the actual inherited genes present in the nucleus of the somatic cells.

What are antigens on red cells?
they are substances present in surface of rbc used to determin bld group and genotype
