Genes usually come in pairs. But they tend to appear in different parts of the chromosome. These genes that appear on a particular chromosome are called alleles. Alleles, give a person a dominant trait that he/she inherited from his/her parents. If an allele is dominantly leaning on the gene side of the mother, one could possibly inherit her blood type or even her colorblindness.</span>

The correct answer is alleles.
While conducting experiments, Mental understood that each trait of the pea plants were controlled by two alleles and depending on those the plant would have different characteristics.

An allele is a variant form of a gene, so for example, in the gene that codes the color of the plant, the alleles could code for green or yellow.

The Hopi, Zuni, and other Southwest indigenous peopleshave a relatively high frequency of albinism resulting from homozygosity f

Ket [755]

Answer:

a. Zero percent

b. Fifty percent

Explanation:

As it has been mentioned in the question that both man and woman are normally pigmented and each one have an albino parent thus both will be heterozygous and their allelic makeup will be as follows -

Man - Aa

Woman - Aa

After a cross between Aa × Aa we get the following result-

One AA, Two Aa and One aa

It is clear that only the aa type of offsprings will be albino.

Out of 4 there is probability of only one to be albino so out of two there will be 50% probability of being albino.

The probability of both sons to be albino will be zero percent.

Minchanka [31]

Answer:

Phosphodiester bonds:"It is a co-v-a-l-e-n-t bond in which a phosphate group joins adjacent carbons through ester linkages."

The 3’-end has a free hydroxyl group at the 3’-carbon of a sugar, and the 5’end has a free hydroxyl group or phosphate group at the 5’-carbon of a sugar.

Explanation:

Option- E: Is The best option to Choose from.

The phosphodiester bond links a 3' carbon to a 5' carbon in DNA and RNA.
