CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -A genotype is an organism’s combination of alleles at a genetic locus. If both alleles are the same, that diploid organism is a homozygote and is thus homozygous; if instead both alleles are different, that organism is a heterozygote and is therefore heterozygous.

Detailed explanation-2: -Typically, there are only two alleles for a gene in a diploid organism. When there is a gene existing in more than two allelic forms, this condition is referred to as multiple allelism.

Detailed explanation-3: -They can be identical, but they can often have slight differences. Alleles, therefore, include all the variant forms of a particular gene.

Detailed explanation-4: -The resulting characteristic is due to both alleles being expressed equally. An example of this is the blood group AB which is the result of codominance of the A and B dominant alleles. Recessive alleles only show their effect if the individual has two copies of the allele (also known as being homozygous?).

Detailed explanation-5: -Alleles can be present on the same chromosome. In such cases, these alleles don’t assort independently and are passed on to the gametes as a unit.
