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
Heterozygous
Dominant
Recessive
Lethal
Dominant allele are expressed in
In Mendel's experiment nature of seed coat, flower colour, position of flower, pod colour, stem height etc. are reffered to as
When a heterozygous dominant is crossed with homozygous recessive than ratio of progeny will be
Genes which code for a pair of contrasting traits are known as ........
The production of gametes by the parents, formation of zygotes, the $\mathrm{F}_{1}$ and $\mathrm{F}_{2}$ plants, can be understood from a diagram called:
