The inheritance of skin color genes is polygenic, meaning that many different genes are inherited and none are dominant, but rather they all work together to create a special blend of genes that you have. This is also influenced by environmental factors such as exposure to sun and similar.

Human skin color is a polygenic trait, which means that multiple gene loci are involved in its expression. It has been shown that there more than 350 genetic loci involved in determining skin color. Because of that, there is the enormous number of possible genotypes for the skin color and as a result, the phenotypes vary from the darkest brown to the lightest hues. Different populations have different allele frequencies of genes for human skin color, and the combination of these allele variations brings about complex and continuous variation in skin coloration. Natural skin color can change due to exposure to sunlight (becomes darker) and that is the way it adapts to intense sunlight irradiation (protection against the UV exposure).

A plate moves 200m in 10,000 years. what is the rate in cm/year
algol13

Answer:

Rate = 2 cm/year

Explanation:

It is given that, a plate moves 200m in 10,000 years. We need to find its rate in cm/year.

We know that, 1 m = 100 cm

200 m = 200 × 100 cm

= 20000 cm

Its rate is given by :

R=\dfrac{20000}{10,000}\\\\R=2\ cm/year

So, the plate is moving at a rate of 2 cm/year.

Huntington Disease is an autosomal recessive condition. Which percentage
Ksju [112]

Answer:

The options to this question are unclear but the answer is: Hh, Hh, hh, hh i.e Hh (50%), hh (50%).

Explanation:

This question involves a single Gene coding for the possession or not of Huntington's disease in humans. The disease is said to be an autosomal recessive condition i.e. it only happens in a recessive state (hh).

According to this question, when a female with Huntington disease (hh) mates with a male that is heterozygous (Hh) for the Huntington trait, the following gametes will be produced by each parent.

hh - h and h

Hh - H and h

Using these gametes in a punnet square (see attached image), the following genotypic combination of offsprings will be produced.

Hh, Hh, hh and hh

Hh = 50%

hh = 50%

Tpy6a [65]

Answer:

The reason is because the moon's orbit about the earth is about 5 degrees off from the earth-sun orbital plane. However, at special times during the year, the earth, moon, and sun do in fact "line up". When the moon blocks the sun or a part of it, it's called a solar eclipse, and it can only happen during the new moon phase.
