What would be the colour of flower in F1 progeny as a result of cross ...
**Explanation:**
In the cross between homozygous red and homozygous white flowered Snapdragon, the flower color in the F1 progeny is expected to be pink.
**Mendelian Inheritance:**
Mendel's law of dominance states that when two pure-breeding individuals with contrasting traits are crossed, the offspring in the F1 generation will display only one of the traits. In this case, red flower color is dominant over white flower color.
**Genotypes of Parental Plants:**
- Homozygous red flowered Snapdragon: RR
- Homozygous white flowered Snapdragon: rr
**Gametes produced by Parental Plants:**
- Homozygous red flowered Snapdragon: R
- Homozygous white flowered Snapdragon: r
**F1 Progeny:**
When the homozygous red flowered Snapdragon (RR) is crossed with the homozygous white flowered Snapdragon (rr), all the F1 progeny will inherit one allele from each parent.
- Male Parent (RR): R
- Female Parent (rr): r
**Genotype of F1 Progeny:**
The genotype of the F1 progeny will be Rr, as they inherit one allele for red flower color (R) from the male parent and one allele for white flower color (r) from the female parent.
**Phenotype of F1 Progeny:**
The phenotype of the F1 progeny is determined by the dominant allele. In this case, red flower color (R) is dominant over white flower color (r). However, when the dominant and recessive alleles combine, they produce an intermediate phenotype. In Snapdragon, the combination of red and white alleles results in pink flower color.
Therefore, the flower color in the F1 progeny of the cross between homozygous red and homozygous white flowered Snapdragon will be pink.
In the cross between homozygous red and homozygous white flowered Snapdragon, the flower color in the F1 progeny is expected to be pink.

What would be the colour of flower in F1 progeny as a result of cross ...
As in this case, formation of PINK colour of flower, indicates that this is INCOMPLETE DOMINANCE. In incomplete dominance , one character(red) is partially expressed and another character remains recessive.
