Answer: A fern gametophyte produces eggs and sperm in archegonium portion and antheridium portion respectively

Ferns are bisexual and go under sexual reproduction. Ferns reproduce by using spores. In haploid phase each of the cells contain only one copy of each chromosome and in the multicellular diploid phase where each of the cell contained two copies of each chromosomes.

The sperms are produced in the antheridium portion and the eggs are produced in the archegonium portion

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

3). Which process can result in increased biomass for a plant: cellular respiration or photosynthesis? Where does the mass come

Karo-lina-s [1.5K]

Photosynthesis results in increased biomass for a plant. I<span>n photosynthesis, carbon dioxide and water yield glucose and oxygen. So, the carbon dioxide and water are taken in and are create a glucose. Glucose can be transformed into organic molecules, such as starch, which will increase biomass.</span>
