Provide explanations of genotypes and phenotypes.
Korvikt [17]
The phenotype is the physical appearance of an organism, while the Genotype is the genetic composition of an organism. Phenotype is observable and are the expression of the genes of an individual. So even the organism with the same species may differ, with a minute difference in their genotype. This is the main difference between the two.

We can notice one’s hair colour, eye colour, height, weight, skin colour, etc. but cannot look at genes responsible for these characters, so the observable physical look is the phenotype while the unnoticed genes responsible for such characters present in the DNA of cell of the individual is genotype.

To explain the above lines, here is the simple example of a pure red colour flowering plant (RR) is crossed with the white colour flowering plant (rr). The result of the Genotype of the F1 generation will be – Rr (Hybrid red colour), and the Phenotype of the F1 generation will be the – Red colour flowering plant.

Genotype and phenotype are the two very closely related and similar-sounding words, but their meaning is different. Our earth has a dynamic variety of organisms, present in soil, water and on land. But as the genome of each organism is different, and so there phenotypes also whether it’s their colour, height, weight or other morphological features.

Represents the presence of the<br> rhesus protein on blood.
Roman55 [17]

AlohaS4

Answer & Explanation:

( Rh Factor ) represents the presence of the Rhesus protein in the blood.

( Rh+ ) blood contains the rhesus protein.

( Rh- ) blood does not contain the rhesus protein.

( Type O ) blood is the universal donor.

( Type AB ) blood is the universal recipient.

( Rh+ ) blood can receive Rh+ or Rh- blood.

( Rh- ) blood can receive Rh- blood.

The parent cell that enters meiosis is diploid, whereas the four daughter cells that result are haploid.
abruzzese [7]

Answer:

option d

Explanation:

Meiosis stage was formerly called the reduction stage involving two divisions; meiosis I and II. After the first stage of meiosis, the ploidy level of each of the daughter cell changes is in an haploid state, meaning here the DNA content has been reduced by half. In humans (2n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23). This haploid state is still maintained by the meiosis II just undergoing the normal mitosis division.

Construct three arguments that support the conclusion that genetic modification of foods is beneficial.
storchak [24]

Explanation:

possible benefits of genetic engineering include:

More nutritious food

Tastier food

Disease- and drought-resistant plants that require fewer environmental resources (such as water and fertilizer)

Less use of pesticides

Increased supply of food with reduced cost and longer shelf life

Faster growing plants and animals

Food with more desirable traits, such as potatoes that produce less of a cancer-causing substance when fried

Medicinal foods that could be used as vaccines or other medicines
