Tortoise shell cats, like the one shown above, are always femaleWhat scientific phenomenon explains the color pattern of
8_murik_8 [283]

Tortoise shell cats can be explained as the offspring from a incomplete dominance cross. Incomplete dominance gives rise to an intermediate phenotype.

The scientific phenomenon that explains the color pattern is X-linked incomplete dominance.

  • As stated earlier, the tortoise shell colour is as a result of incomplete dominance but as it exists only in females, the inheritance is X linked.
  • This means the tortoise shell colour is inherited in the heterozygous condition as females have two X (XX) and males (XY) can only be either of the parent's true breeding genotype.

hjlf
The initials will still be 4 feet above the ground.

Trees do not grow from the bottom up. At the branch tips there is meristem tissue, so called the apical meristem. Trees grow in height from these apical meristems, so trees grow from the top and the initials on the bottom of the tree will stay at the same height above the ground.

An example of the role of cultural practices shaping natural selection on genes that affect human health concerns
kaheart [24]

Answer:

The correct answer here is D) None of the above

Explanation:

Lactose intolerance and sucrose intolerance in themselves are not practices but side effects of practices that affect health concerns.

For instance, research shows that cultures with a long history of dairy farming and milk drinking or at least a history of drinking milk have a much higher likelihood to be <u>lactose tolerant</u> than those who don't. And when they can tolerate lactose their bodies take note of this and records the same in their genetic databank.

Cheers!
