What is the difference between heterozygous and heterozygote?
Heterozygous. A diploid organism is heterozygous at a deteriorate locus when its cells hold two particularize alleles (one wild-type allele and one mutant allele) of a gene. The mixture or organism is named a heterozygote specifically for the allele in ask and accordingly heterozygosity refers to a specific genotype.
How does a heterozygous advantage work?
A heterozygote gain describes the occurrence in which the heterozygous genotype has a higher referring_to inaptness sooner_than either the homozygous prevailing or homozygous recessive genotype. The specific occurrence of heterozygote gain due to a one locus is mysterious as overdominance.
What does heterozygote superiority mean?

What is the probability of a heterozygous offspring?
25% The possibilities are summarized: accordingly is a 50% x 50% = 25% likelihood that twain of the offspring’s alleles are dominant. accordingly is a 50% x 50% = 25% likelihood that twain of the offspring’s alleles are recessive. accordingly is a 50% x 50% + 50% x 50% = 25% + 25% = 50% likelihood that the offspring is heterozygous.
What is homozygous psychology?
