AaBb usually, but can also be AAbb or aaBB depending on what they ask you is heterozygous.
To be heterozygous for one trait, it's AaBb.
To have a heterozygous genotype, unless specified, it can be any of the above.
All of these choices are possible combinations in a dihybrid cross
A heterozygous genotype includes two different alleles.
RrYy
The heterozygous genotype
The genotype of the tall pea plant is heterozygous
"Heterozygous" means having one copy each of the dominant and the recessive allele governing a particular trait."Dihybrid" means that you are following the inheritance of two traits ("di-" = 2).For example: in the peas that Mendel studied, round seeds (allele R) are dominant over wrinkled (r). So a heterozygous plant has the genotype Rr. Yellow seeds (Y) are dominant over green (y). In experiments following these two traits (seed shape and seed color) a dihybrid heterozygous individual therefore has the genotype RrYy.A dihybrid cross involves observation of two traits, e.g.RRYY x rryywhich would yield an F1 entirely made up of RrYy individuals.
Dd is the heterozygous genotype for dimples.
All of these choices are possible combinations in a dihybrid cross

A heterozygous genotype includes two different alleles.
RrYy
A heterozygous genotype
A Heterozygous genotype means an organism that has both the dominant and the recessive gene.
A heterozygous genotype, is the genetic makeup of different alleles.
