Darya [45]

Answer:

Option A , Genome

Explanation:

Microarrays that contains array of single stranded DNA are used to study thousands of gene expression for all the genes of a genome and are usually termed as DNA miscroarrays. These microarrays being single stranded allows attachment of complementary DNA strand to bind to their surface. The mRNA from the cell is extracted and converted into cDNA which is further used for DNA cloning.

Hence, option A is correct

If someone with auburn hair has children with someone with red hair (but whose mother had black hair ) what are the genotype and
tensa zangetsu [6.8K]

The phenotype is - 75 % red and 25 %brown.

The genotype is hRhR - 25%

hBkhR - 50%

hBrhBk - 25%.

<h3><u>Explanation:</u></h3>

The cross given here is a simple dominant - recessive relationship between the three types of alleles of hair colour. The genes of this characteristics are present in autosomes, so will be segregated equally among all the sexes of the offsprings.

Now the genotype of auburn and red with black mother is given. So during gametogenesis, the gametes from the parents will be

Father - hBr and hR

Mother - hBk and hR

So, the probable combinations are hBrhBk, hBrhR and hBkhR.

The frequency of the combinations are 25%, 25% and 50% respectively.

The phenotypic ratio will be red : brown as 3:1.
