Answer:

a) genetics and heredity: Genetics can be described as the study of genome or DNA of an organism. Heredity refers to the traits which are passed on from the parents to the offsprings. Not all of the genome of an individual is similar to the parents. Hence, genetics refers to the genome of an individual and heredity refers to the traits which pass from the parents to the child.

b) Dominant and recessive trait: A dominant trait is caused due to a dominant allele. A dominant allele is the allele which can mask the effect of the other recessive allele. Hence, a person can be homozygous or heterozygous for the dominant trait. A recessive trait arises due to the recessive allele. A recessive allele is the allele which gets masked by the dominant allele.

Pure and hybrid: A pure offsprings contains the same genetic character for a trait. It is a homozygous offspring. A hybrind offspring contains different alleles or genetic characters and is heterozygous.

G1, S & G2 phase make up this part of the cell cycle ?

ratelena [41]

Answer:

Interphase

Explanation:

Interphase is the G1, or gap 1, phase in which the new cell grows and carries out its functions in the body; the S, or synthesis, phase when the chromosomes replicate; and the G2, or gap 2, phase, when the cell grows further and prepares to divide.

Que signifie ADN et comment on le prouve?

irakobra [83]

Answer:

L'ADN (acide désoxyribonucléique) est un type d'acide nucléique qui se distingue par le stockage de l'information génétique de la grande majorité des êtres vivants. Cette molécule est formée de nucléotides et a généralement la forme d'une double hélice.

Il est nécessaire de prélever des échantillons de certains fluides corporels qui peuvent être du sang, de la salive, des ongles, des cheveux ou du sperme. À l'aide de techniques de laboratoire sophistiquées, l'ADN des échantillons est isolé, puis une cartographie est effectuée, ce qui est fait par des équipements appelés "Séquenceurs d'ADN".

Pour le prouver, normalement le rapport d'un examen ADN apporte quels gènes et chromosomes ont été étudiés et l'analyse du généticien à leur sujet. Les résultats sont présentés dans des rapports simples et clairs. Dans les examens de paternité, le résultat est toujours comparatif.

J'espère t'avoir aidé, bonnes études !

What group of animals has flexible hands and feet, large brains in relation to body size, forward-looking eyes, and arms that ca

Lana71 [14]

<h2>Primates </h2>

Explanation:

Primates are a group of animals has flexible hands and feet, large brains in relation to body size, forward-looking eyes, and arms that can rotate in a circle around the shoulder joint

Primates include the lemurs,lorises,monkeys,apes and humans
The order Primates, with its 300 or more species, is the third most diverse order of mammals, after rodents and bats
The Primates order is divided informally into three main groups: prosimians, monkeys of the New World, and monkeys and apes of the Old World
All primates have five fingers (pentadactyly), a generalized dental pattern, and a primitive body plan
Another distinguishing feature of primates is fingernails
Opposing thumbs are also a characteristic primate feature
When compared with body weight, the primate brain is larger than that of other terrestrial mammals, and it has a fissure unique to primates that separates the first and second visual areas on each side of the brain
The eyes face forward in all primates so that the eyes visual fields overlap
Fossils of the earliest primates date to the Early Eocene Epoch (56 million to 40 million years ago) or perhaps to the Late Paleocene Epoch (59 million to 56 million years ago)
