Give differences : Homozygous and Heterozygous
Hence, in plants the pair of alleles for height would be $TT$ , $Tt$ or $tt$ . Mendel also proposed that in a true breeding, tall or dwarf pea variety the allelic pair of genes for height are identical or homozygous, $TT$ and $tt$, respectively.
In other words the hybrids have $Tt$. Since these hybrids contain alleles which express contrasting traits, the plants are heterozygous.
Which of the following is genotypic ratio of Mendel's monohybrid cross
Test cross involves
The leaf colour of certain plants is controlled by one gene. For that gene, the allele $G =$ orange and $g =$ green. You have a plant with orange leaves, but do not know whether that plant's genotype is $GG$ or $Gg.$
If you cross your unknown plant with one of the plants whose genotype is listed below, you will be able to determine your unknown's genotype. With which plant would you cross it?
Discuss the genetic basis of wrinkled phenotype of pea seed.
Find out the percentage of dominant phenotype in cross between $P_p$ and $P_p$. $P-$dominant, $p-$recessive
