Sexual reproduction offers genetic variation, as the offspring are a combination of 2 sets of genes opposed to one. This ultimately leads to evolution and the adaption to changing environments :)
Answer: The shoot grows up towards the sunlight is Positive Phototropism
The root grows down the soil is Positively Geotropism / positive gravitropism.
happy to help again :)
Genetic alteration refers to altering DNA sequence. Gene alteration forms genetically modified products that modifies the gene sequence. DNA consist of two long chains of nucleotides that are twisted and joined together in hydrogen bonds. These DNA cannot be altered in nature but gene expression can be altered.
Answer:
The correct answer is -
P1: SSyy
p2: ssYY
Explanation:
In the given question it is given that S is the allele for the dominant trait of spherical shape over s allele of dented shape and similarly Yellow pea seed is dominant over y green seed.
It is given that parent 1 or p1 is true breeding for green spherical shaped seeds which means it has two alleles of the same gene that are SSyy (S for spherical and y for green) and parent 2 or p2 is a pure bred plant with yellow dented shaped seeds that would be ssYY.
