The ratio of yellow seed phenotype with green seed color seed offsprings will be 4:0.
Explanation:
Given that:
Dominant trait is Y (yellow seed color)
recessive trait is y (green seeds color)
cross between YY and yy, According Mendelian Genetics dominant trait will be seen in phenotype as it masks the effect of recessive gene.
Punnet square shows that:
Y Y
y Yy Yy
y Yy Yy
All the plants produced will be tall phenotype.
The yellow seed plant plants will be heterozygous i.e Yy
the phenotype ratio is 4:0
The genotype ratio is 4:0
The genotype of the offspring is Yy
phenotype is yellow colored seed plant.
Answer:
only appear in veg plants
Explanation:
Unlike other forms of asexual reproduction in plants such as vegetative plant propagation via cuttings, apomixis is asexual reproduction via seeds. In the case of most dandelions (i.e., Taraxacum officinale), the embryo in the seed forms without meiosis, thus the offsping are genetically identical to the parent.
