Answer:

Plant cells have a cell wall, a large central vacuole, and chloroplasts, but a animal cell does not have those things.

Nucleus; contains DNA

Lysosome; breaks down nutrients and wastes

Vacuole; storage

Centrosome; has a role in Mitosis to seperate chromosomes

Chloroplast; photosynthesis

Endoplastic Reticulum; transport nutrients within the cell

Ribosome; protein synthesis

Mitochondria; breaks down glucose into ATP energy

Cell wall; a rigid membrane found in plants and some bacteria

Golgi apparatus; packages proteins made, exocytosis

Cell membrane; a flexible mebrane around eukaryotic cells

In guinea pigs hair straightness or curliness is thought to be governed by a single pair of alleles showing incomplete dominance

Nimfa-mama [501]

Answer:

Frequency of allele S is p $= 0.4939$

Frequency of allele C is q $= 0.666$

The population is not in Hardy-Weinberg equilibrium

Explanation:

Given -

Number of individuals with straight hair $= 244$

Number of individuals with curly hair $= 444$

Number of individuals with Wavy hair $= 312$

Let "p" represents the frequency for allele for straight hair and "q" represents the frequency for allele for curly hair

$p^2$ represents the frequency of genotype "SS"

$p^{2} = \frac{244}{1000} \\= 0.244$

$q^2$ represents the frequency of genotype "CC"

$p^{2} = \frac{444}{1000} \\= 0.444$

$2pq$ represents the frequency of genotype "SC"

$2pq = \frac{312}{1000} \\= 0.312$

Frequency of allele S is p

$= \sqrt{0.244} \\= 0.4939$

Frequency of allele C is q

tex]= \sqrt{0.444} \\= 0.666[/tex]

For being in Hardy Weinberg's equation-

$p+q=1\\$

Substituting the values in above equation, we get -

$0.4939+0.666\neq 1$

hence, the population is not in Hardy-Weinberg equilibrium

Write a Sentence explaining the connection between dominant and recessive

earnstyle [38]

Answer:

The most common interaction between alleles is a dominant/recessive relationship. An allele of a gene is said to be dominant when it effectively overrules the other (recessive) allele. Eye colour and blood groups are both examples of dominant/recessive gene relationships.

The main difference between dominant and recessive trait is that dominant genes always passes the dominant behavior genes while the recessive ones pass the recessive behavior genes. In fact, the dominant genes are said to be more likely to pass to future generations, while the recessive ones are less likely to do that.
