Answer:
500
Explanation:
According to the given information, the total number of albino people in the population= 1000/4 = 250.
Since albinism is an autosomal recessive trait, the genotype of albino people would be homozygous recessive. Therefore, the frequency of homozygous recessive genotype in the population (q2) = 250/1000= 0.25.
The frequency of recessive allele (q) = square root of 0.25 = 0.5
Since p+q=1. So, p (frequency of dominant allele) = 1-q = 1-0.5 = 0.5
Frequency of heterozygotes in the population= 2pq = 2 x 0.5 x 0.5 = 0.5 or 50%
Therefore, expected number of heterozygotes in the given population= 50% of 1000 = 500
A chemical substance that an organism requires to live. a nutrient that is scarce or cycles slowly through an ecosystem. ensures that nutrients will be circulated throughout the biosphere.
They need to have the exact copy of the cell, so it does takes time.
Ribosomes - Make protein
Golgi Apparatus - Make, process, and package proteins
Nucleus - Stores the DNA and coordinates the cell's activities
Mitochondria - Make energy out of food
Vacuole - Storage for food and water
Lysosome - Contains digestive enzymes that help break down food
Plant cells (only) -
Cell wall - Protection and support
Chloroplast - Uses sunlight to create food using photosynthesis
I hope this helps :)
The umbra is the innermost and dark part of the shadow where like it’s created by any light source and is completely blocked by the occluding body. It’s a Latin term hope this helps man!
