Describe how genetic information is passed on from parent to a child

Biology
1 answer:
jarptica [38.1K]3 years ago

Answer:

Chromosomes are passed from parents to offspring via sperm and eggs. The specific kind of chromosome that contains a gene determines how that gene is inherited. ... Consequently, each person has two copies (alleles) of every gene carried on an autosome: one inherited from their father and one from their mother.

Like chromosomes, genes also come in pairs. Each of your parents has two copies of each of their genes, and each parent passes along just one copy to make up the genes you have. Genes that are passed on to you determine many of your traits, such as your hair color and skin color

A recessive allele for blue eyes (b) has a frequency of .3 in population 1 and a frequency of .15 in population 2. Pollution cau
tia_tia [17]

Answer:

The frequency of blue eyes in population 2 after the migration is q₂´ = 0.195 ≅ 0.2

Explanation:

Whenever migration, m, occurs between two populations, there is genetic flow going on. Genetic flow is an evolutive strength only if migration > 0 and if the allelic frequency in one generation is different from the allelic frequency in the next generation.

Genetic flow acts homogenizing the allelic frequencies between the two populations, and it might introduce variability into the new one.

For genetic flow to be possible, there needs not only the movement of the genes from one population to the other but also the reproduction process on the new population. Hence, it involves an interaction between the dispersion pattern and the reproductive system.<u> </u>

<u>Available data:</u>

  • Population 1 → frequency of the recessive allele b = 0.3
  • Population 2 → frequency of the recessive allele b = 0.15
  • m = proportion of gametes coming from the population 1  = 30% = 0.3
  • <em>1-m = proportion of gametes that remain in the population</em>
  • <em>p = frequency of the dominant allele in population 1 before migration</em>
  • <em>q = frequency of the recessive allele in population 1 before migration</em>
  • <em>p´ = frequency of the dominant allele in population 2 after migration</em>
  • <em>q´ = frequency of the recessive allele in population 2 after migration</em>

To calculate the frequencies of the gametes (p1, q1, p2, q2) after migration, we can use the following equations:

  • p₁’ = p₁ (1 - m) + p₂ x m
  • q₁´ = q₁ (1 - m) + q₂ x m
  • p₂’ = p₂ (1-m) + p₁ x m  
  • q₂´ = q₂ (1 - m) + q₁ x m

So to know the frequency of blue eyes in population 2 after the migration, we just need to replace the terms in the equation for the given values, and then calculate q₂´.

q₂´ = q₂ (1 - m) + q₁ x m

q₂´ = 0.15 (1 - 0.03) + 0.3 x 0.3

q₂´ = 0.105 + 0.09    

q₂´ = 0.195 ≅ 0.2

This is the cycling of nutrients among soil, litter,plant roots, and above-ground plant parts.
kifflom [539]

Answer:

Internal Cycling

Explanation:

Internal cycling starts when the nutrients transform into ecosystems. The plants through their roots take the necessary ingredients and built them in the tissues. When tissues grow, the nutrients go back to the ground in the form of dead organic matter.

Microbes transform the organic nutrients into minerals, which are again available to the plants.

malfutka [58]

Answer:

In cancer, cells loss their adhesion because protein expression involved in this process is dysregulated

Studies suggest that cell junctions are critical for cancer progression and metastasis

Finally, cancer cells modify the extracellular matrix since this matrix may act as a barrier for the migration of cancer cells
