violet flower was crossed with white flower. Work out the cross till F2 generation (violet is dominant over white). Find out possible phenotype &genotype at respective ratios
Answers
Answer:
Explanation:
Heterozygous Purple flower - Pp
Gametes : P and p
Recessive white flower: pp
Gametes: p
Fusion thus yields: Pp (Purple) and pp (white)
The ratio is 1:1
Hence, it is 50% purple and 50% white.
Answer:
The described cross is a dihybrid cross that displays two characters ' concurrent inheritance. This is also called inheritance as a dihybrid.
Di hybrid inheritance is the experimentation with its four contrasting traits of two features. For example, dihybrid inheritance includes a pea plant producing axial and purple (AA and WW) flowers crossing with a plant generating terminal and white (aa and ww) flowers. Axial and violet flowers (A and a, W and w) are produced by F1 progeny in which axial and violet are dominant features. Similar to their relatives, F2 progeny produced axial and purple flowers, while some produced terminal and white flowers. A mono hybrid cross is the hybrid of two people with homozygous genotypes resulting in the reverse phenotype for a certain genetic trait." "The cross between two mono hybrid characteristics (TT and tt) is called a mono-hybrid cross. A Punnett Square can readily display it. Geneticists use mono-hybrid cross to observe how homozygous offspring express heterozygous genotypes inherited from their parents.
