DNA microarray uses 20-40 sequence-specific oligonucleotides as probes to identify the SNP.
DNA microarray is a technique used to measure gene expression. It works on the principle of hybridization.
The genome of the reference organism is attached to a solid surface (silicon chip). The DNA of the test organism is made to hydride with the reference organism. Depending on the level of hybridization the fluorescent or the chemiluminescent is measured to identify the expression.
Single nucleotide polymorphism (SNP) is the change in the single nucleotide of the genome. SNPs can be identified with the help of DNA microarray.

Answer:
This Punnett square shows<u> incomplete dominance.</u>
Explanation:
The homozygous red flower has two dominant red alleles, and these are represented by the letters RR. The homozygous white flower is represented by rr. Their offspring are all heterozygous Rr, and they have pink flowers. This is the first filial generation, or F1. When the F1 generation cross-pollinates, their offspring will be RR, Rr, and rr in a 1:2:1 ratio. Some of their offspring (the F2 generation) will inherit two R alleles, some will inherit two r alleles, and some will inherit both.

Answer:
a. all tall
Explanation:
If genotypically one of the parents is homozygous dominant and another one is heterozygous for plant height then phenotypically all their progeny will be tall.
Let us suppose, 'T' represents dominant allele and 't' represents recessive allele. Then the genotype of one parent who is homozygous dominant will be TT and genotype of another parent who is heterozygous will be Tt.
The cross is depicted in the attachment.
Here it may also be noted that genotypically two of the progeny will be homozygous dominant while two of the progeny will be heterozygous but phenotypically all the progeny will be 'tall'.
Answer: it increases
Explanation:
On average, the temperature increases by about 25°C for every kilometer of depth.
