The important things to remember are that chromosomes as well as genes occur in ...$A$.... The two alleles of a gene pair are located on homologous sites on ...$B$... chromosomes
Choose the correct choice for $A$ and $B$
$A$-single, $B$-analogous
$A$-pair, $B$-analogous
$A$-pair, $B$-homozygous
$A$-single, $B$-heterozygous
If a homozygous red-flowered plant is crossed with a homozygous white-flowered plant, the offspring would be
Test cross involves
When a true breeding pea plant that has yellow seeds is pollinated by a plant that has green seeds, all the $F_1$ plants have yellow seeds. This means that the allele for yellow is
In a dihybrid cross $80$ plants are obtained. The ratio of homozygous and heterozygous shall be
Alleles are
