Answer:
Polygenic inheritance is determined by multiple Genes located at different loci on different chromosomes.
Polygenic inheritance happens when an individual posses quantitative traits that become a variation compared to the parent's traits.
This phenomenon happens due to the combination of two or more genes that resulted in the characteristics that considered as the combination of both parents' characteristic.

what will happen if the number of organisms decreased?
Answer:
it will affect the ecosystem in a bad way
Answer:
They would starve and die unless they could move to another habitat. All the other animals in the food web would die too, because their food supplies would have gone. The populations of the consumers would fall as the population of the producer fell.
Explanation:
A F1 pea plant carries Yy alleles for seed color. Explain
what would happen to these alleles during gamete
formation
Answer:
During the formation of the gametes (i.e. meiosis) we have the separation of the sister chromatids and the independent segregation of the alleles: this means that one of the gametes will carry the "allele Y" and the other the 'y allele"

La ________ es un proceso de unión de ______, llamados también células ______________. a. Reproducción - organismos - diploides. b. Reproducción - moléculas - somáticas c. Fecundación - individuos - progenitores d. Fecundación - gametos - haploide
Respuesta:
La fecundación es un proceso de unión de gametos, llamados también células haploides.
La correcta es la D.
Explicación:
El proceso por el cual es posible la reproducción y la continuación de nuestra especie se llama fecundación. La fecundación se produce cuando el gameto masculino, el espermatozoide, toma contacto con el gameto femenino, el ovocito.
Los gametos son células haploides, lo que significa que tienen 23 cromosomas - a diferencia de las células somáticas, que son diploides y tienen dos juegos de 23 cromosomas (46 en total). Esto es importante para que cuando se fusionen ambos gametos, la suma de los cromosomas sea siempre 46.
La manera en la que los gametos obtienen 23 cromosomas en lugar de 46 es gracias al proceso de meiosis.
Cuando se produce la fecundación, la célula resultante será el cigoto que, a lo largo de aproximadamente 40 semanas se desarrollará en el útero de su madre.
Consider a population of 100 annual wildflowers, some yellow, some red. It is like other real populations, its gene pool is changing. For each of the scenarios below state which of the Hardy-Weinberg conditions the population deviates from, and explain what agent of microevolution causes the gene pool to change
Answer:
From normal to hybrid or different state.
Explanation:
According to Hardy-Weinberg conditions, the population deviates from present state to hybrid because of the change of gene pool. Genetic drift, natural selection and mutation are considered as agent of microevolution that is responsible for the change in gene pool. If the change in gene pool occurs the form and structure of population of organisms has to be change in its appearance.

Which of the following statements about how surface currents affect climate is false?
Because surface currents are always warm, they warm the land they travel closest to.
A periodic change in the location of warm and cool surface waters in the Pacific Ocean changes global weather patterns.

England experiences warmer temperatures than other countries at the same latitude because of the warming effect of a surface current.

Hemophilia is a sex-linked recessive trait. If a man with hemophilia marries a woman who is a carrier for the trait, what are the predicted
phenotypes for their children?
• A1 carrier male: 1 affected male: 1 carrier female: 1 affected female
B 1 carrier male: 1 affected male: 1 carrier female: 1 normal female
C1 normal male: 1 affected male: 1 carrier female: 1 normal female
OD 1 normal male: 1 affected male: 1 carrier female: 1 affected female
Answer:
c i hope it works
Explanation:
No sons of a man with hemophilia will have hemophilia.
All daughters of a man with hemophilia will be carriers (called obligate carriers).
If a carrier has a son, the son has a 50% chance of having hemophilia.
If a carrier has a daughter, the daughter has a 50% chance of being a carrier.

How is the clavicle, or collarbones, of a chicken-shaped? Using the diagram, indicate which group of dinosaurs has a furcula similar to that of chicken. PLZ MAKE AN ELABORATE EXPLANATION!!!
Answer:
The clavicles of a chicken are Y-shaped.
Many similarities are noted in the clavicles of a chicken and theropod. Both clavicles are fused to form a single V-shaped structure.
The clavicles of a chicken are Y-shaped.
What is collarbone?One of the primary bones in the shoulder, the collarbone, can break and suffer from a clavicle fracture. About 5% of all adult fractures are of this type, making it a reasonably common fracture.
The majority of clavicle fractures happen when the bone is sufficiently compressed—either by a fall onto the shoulder or an outstretched arm—to snap or break. With a broken collarbone, your arm may be difficult to move and may be quite painful.
Wearing a sling to prevent the arm and shoulder from moving while the bone heals is a common treatment for clavicle fractures. However, in some clavicle fractures, the damage causes the bone fragments to shift drastically out of position.
Therefore, The clavicles of a chicken are Y-shaped.
