Test cross | NMDCAT 2021

About This Video!
Mendel devised a cross called test cross, which is used to test the genotype of an
individual showing a dominant phenotype. It is a mating in which an individual showing
a dominant phenotype is crossed with an individual showing its recessive phenotype.
This cross inds out the homozygous or heterozygous nature of the genotype
1.If the seed is homozygous round(RR) it
will grow into a pea plant that forms all
gametes with only `R` allele.Wrinkled
seed plant is always homozygous
recessive.it will form all gametes with
`r` allele.Fertilization will result in 100%
round seed progeny.
2.If the seed is heterozygous round (Rr), it
will grow into a plant that forms half the
gametes, with ‘R`and half with `r` allele.
Wrinkled seed plant will form only `r`
type of gametes. Fertilization will result
into 50% round and 50% wrinkled seed
progeny. Even a single wrinkled seed in
the progeny is a convincing proof for
Heterozygous nature of the round
parent.
