When true breeding tall plants are crossed with hybrid tall plants the offspring are?
When true breeding tall plants are crossed with hybrid tall plants the offspring are?
Biology 2nd semester final
| Question | Answer |
|---|---|
| If you made a punnett square showing Gregor Mendel’s cross between true breeding tall plants and true breeding short plants, the square would show that the offspring had | Genotype that was different from that of both parents |
What plants are found in F1 generation?
The F1 generation results from cross-pollination of two parent (P) plants, and contained all purple flowers. The F2 generation results from self-pollination of F1 plants, and contained 75% purple flowers and 25% white flowers. This type of experiment is known as a monohybrid cross.
What do the plants of F1 generation look like?
As tallness and purple colour are dominant characters, all the offspring of F1 generation will look tall with purple colour of flowers. Was this answer helpful?
Why is the progeny always tell when a tall pea plant is crossed with a?
The trait that can express itself in homozygous condition only is known as recessive trait. The cross between tall and short pea plant produces the tall progeny. The tall progeny is present in heterozygous condition and the tall trait is dominant that express itself and hides the expression of short trait.
When heterozygous tall plants were self crossed the result obtained were both tall and short plant?
Assertion (A): When heterozygous tall plants were self crossed, the result obtained were both tall and short plant. Reason (R): Heterozygous plants contain both dominant and recessive alleles.
When f1 plants heterozygous for tallness is Selfed f2 generation has both tall and dwarf plants this proves the principle of?
This proves the principle of. or. when hytrozygous talll lants are self-pollinated than tall and dwarf plants are obtained this is explain to. This is the law of segregation.
When a tall plant was self pollinated one-fourth of the progeny were dwarf give the genotype of the parent and dwarf progenies?
When a tall pea plant was self-pollinated, one-fourth of the progeny were dwarf. Give the genotype of the parent and dwarf progenies. Ans. Genotype of parent is Tt and the genotype of dwarf progenies is tt.
Why in nature do we find more tall pea plants than dwarf pea plants?
In nature, tall pea plant is found more because it is a dominant trait. Mendel came to know this when he performed cross between pure breeding tall ( TT) and pure breeding dwarf plant ( tt). He observed that all the plants were tall in the F1 generation. Therefore, it is found more in the nature.
