Consider a population of 425 diploid giant Sequoia trees. In this population, you observe the following genotypic counts: 100 ho
Lemur [1.5K]

Answer:

q = 0.42

Explanation:

This question is an example of Hardy-Weinberg question and there are two equations necessary to carry out this question;

p + q = 1

p² + 2pq + q²  = 1

where;

p = the frequency of the dominant allele

q =  the frequency of the recessive allele

p² = the frequency of individuals with homozygous dominant genotype

2pq  = the frequency of individuals with heterozygous genotype

q² = frequency of individuals with the homozygous recessive genotype

Since the total  population = 425

q² = \frac{individuals with recessive genotype}{Total Population}

= \frac{75}{425}

q² = 0.1765            

To find q; we need to square root both side to           eliminate the square from  q².

∴ \sqrt{q^2}=\sqrt{0.1765}

q = 0.4201

q = 0.42       (to two decimal places)

Determine whether each of the following is a characteristic of the life cycle of a seed plant, a seedless plant, or both. Double
Gnoma [55]

Double fertilization-plants with seeds (flowering plants), two male gametes joining with female gametophyte

Gametophyte generation-both (haploid, sexual stage stage-gametophyte, and the diploid stage that produces spores – sporophyte)

Endosperm formed-plants with seed because it is a tissue formed inside the seed which surrounds the embryo and provides nutrition

Mitosis-both (mitosis occurres in spores)

Spores develop into gametophytes-both but, in seedless plants sporophyte produces spores that will develop into a new organism (multicellular gametophyte) using mitosis, while spores of seed plants are produced internally and develop into more complex structures.

Nana76 [90]
The investigators could distinguish human hair from animal hair by the patter of pigmentation and by the medullary index.
The pigmentation in human hairs is denser toward the cuticle, whereas in animal hair is denser toward the medulla. Human hairs are usually one colour throughout the whole length, while animal hairs may change colour suddenly.
The medulla in humans is thinner than in animals: the medullary index for human hairs is 0.33 or less; the medullary index for animal hairs is 0.5 or more.
