Human albinism is an autosomal recessive trait. Suppose that you find a village in the Andes where 1/4 of the population is albi

no. If the population size is 1000 and the population is in Hardy-Weinberg equilibrium with respect to this trait, how many individuals are expected to be heterozygotes?

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

What is one potential result of climate change that could inhibit (reduce) kelp's ability to do photosynthesis?
Bogdan [553]
One potential result of climate change is greenhouse effect that is defined as the accumulation of carbon dioxide in the atmosphere that retains heat radiated from the sun. While this can seem beneficial because plants use carbon dioxide in photosynthesis, elevated levels of carbon dioxide actually inhibit photosynthetic mechanisms (Xu, 2015).

Law vs theory compare and contrast please really need help !!!
Sergeu [11.5K]
Some are:
-laws tell how
- laws are proven true
- Theories attempt to explain
- Theories are developed based on likely true things, but not necessarily proven
- hypothesis is an educated guess
- hypothesis is made before your test/experiment.
- laws are formed after tests and experiements.
- Theories are often based off of tests/experiment, but again, not necessarily proven to be true.

Explain what, if any, is the issue facing DNA polymerase in regards to its 5’->3’ activity when replicating DNA.
Ymorist [56]

Answer:

The two strands of DNA are replicated in different ways

Explanation:

DNA replication is a process that occurs during the S phase of the cell cycle that consists of making two identical copies of the double-stranded DNA molecule, which subsequently are distributed in the daughter cells during cell division. During this process, DNA polymerase can add nucleotides in 5' to 3' direction, but not in 3' to 5' direction. In consequence, the DNA strand that has 3’ to 5’ directionality can be synthesized directly, while the DNA template strand that has 5’ to 3’ directionality can't be synthesized in a continuous manner and thereby it is created by adding small DNA fragments, which are known as Okazaki fragments (150-200 nucleotides in size).
