Somatic cells in elephants have 56 chromosomes. How many chromosomes would be carried by the gametes produced by elephants

You are a dog breeder and are interested in two traits that you believe are inherited by simple genetic loci glossy (G) coat is

Paul [167]

Answer:

GL, Gl, gL, and gl

Explanation:

The mom is glossy long haired. Since glossy (G) is dominant over to dull (g) and long hair (L) is dominant to short hair (l), the possible genotypes of the mom would be:

GGLL, GgLL, GGLl, or GgLl

The dad is dull and short haired, the genotype would be ggll.

GGLL x ggll

Progeny = all GgLl (all glossy long haired)

GgLL x ggll

Progeny = 8 GgLl, 8 ggLi (glossy long haired and dull long haired)

GGLl x ggll

Progeny = 8 GgLl, 8 Ggll (glossy long haired and glossy short haired)

GgLl x ggll

Progeny = 4 GgLl, 4 Ggll, 4 ggLl, 4 ggll (glossy long, glossy short, dull long, and dull short)

Only a cross of ggll with GgLl produced the offspring that cover the phenotypic range shown in the illustration. Hence, the genotype of the mom is GgLl.

The parental gametes produced by the mom would be; GL, Gl, gL, and gl

The most common form of genetic disorder that causes the fetus to spontaneously abort involves _____.

Tomtit [17]

An incorrect number of chromosomes is the most common form of genetic disorder that causes the fetus to spontaneously abort. The human cells normally contain 23 pairs of chromosomes, for a total of 46 chromosomes in each cell. Error in one or more of the meiosis, mitosis, maternal age, or environment are the possible cause of the chromosome abnormalities. These abnormalities in the number chromosomes can cause problems with development, growth and function of the body's systems. These changes can occur in early fetal development, or in any cell after birth during the formation of reproductive cells (sperm and eggs).

The arctic fox is different from the brown fox. The color of the arctic fox’s fur changes to brown during the summer. The fur re

Fofino [41]

The Arctic Fox lives in the Arctic Tundra (more or less around Alaska, Iceland I think, and other places like that). During the winter, their fur is very thick and solid white (not always SOLID but generally speaking). During the summer and spring, their fur turns brown.

1. Of course, during the winter in those regions, it's going to be snowing and ice is going to be all over the ground. By having a white coat, they're able to blend in and hide from predators, such as the Arctic Wolf and Polar Bears. By turning brown, they'll be able to blend in with the dirt after the snow and ice melts, and again, hide from predators. For the other fox, their brown coat blends in with the dirt, trees, dead leaves, etc. and they'll be able to hide from prey and predators alike.

2. The Arctic Fox also has very thick fur during the winter, which allows it to survive the extreme temperatures. They also dig burrows in the snow for shelter in blizzards. This gives them the ability to survive natural disasters (at least one of them).

I can't think of a third one but these should give you a pretty good idea of how their adaptations help them survive. I really love the Arctic fox so I know quite a bit about them. I really hope this helps you.

horsena [70]

The function of the lens is that it allows light rays to focus into the retina. They are composed of fluids that contains lots of nutrients for the lens to gain from it and cleanses dirt if it comes in contact the eye. Overtime, this lens, will slowly degrade as its fluid will start to lose.
