What least likely to be a source of genetic variation among living organisms

Biology
1 answer:
crimeas [40]3 years ago
4 0

Answer:

The least likely to be a source of genetic variation among living organisms is  asexual reproduction. Asexual reproduction is a kind of reproduction that does not include fertilization process of two gametes: female and male but only includes parts of plants or cells. In this case, variation is minimized

Where is the part that will develop into a fruit on a male flower?
Arte-miy333 [17]
Actually, flowers haven't genders, like " woow, that's a male flower". WROOONG. Flowers have, indeed, parts of themselves that are their male reproductive system and their female <span>reproductive system. Butt* the part of the flower that develop, as you said, into a fruit it's the ovary, after being pollinated by pollen from the anther of another flower (ovary is the female part of the flower and the anthers are the male part)

*that's a joke, ok?

In biological macromolecules like proteins, the hydrophobic residues tend to clump together in the interior of the folded struct
Brut [27]

Answer:

The water and polar residues cannot bind to the hydrophobic ones, so in the lowest energy state the hydrophobic residues are pushed together in the middle.

You sampled 1000 individuals from a population of mosquitoes to test whether they are in Hardy-Weinberg Equilibrium for a gene D
Marysya12 [62]

Answer:

The population is not following the Hardy-Weinberg equilibrium.

Explanation:

Hardy-Weinberg  proposed that the population will remain in the equilibrium if they are not affected with the external natural force like genetic drift, mutation and many others. The gene pool of a population will remain in equilibrium state for generations.

The mathematical expression for the Hardy-Weinberg are

Genotypic frequency is p²+q²+2pq=1

Allele frequency is p+q=1

where p-dominant allele,

q-recessive allele

Therefore,calculating expected frequency of allele q,

q² (recessive genotype)-  q²+2pq/1000

= 22+188/1000

=210/1000

= 0.21

q= 0.45

Calculating expected frequency of allele p,

Using p+q=1

p=1-q

p= 0.55 (expected)

Calculating observed value of frequency of p,

p²= p²+2pq/1000

= 790+188/1000

= 978/1000

= 0.978

p = 0.988 (observed)

Since the expected frequency does not match the observed frequency therefore the population is not under the Hardy-Weinberg equilibrium and the gene pool is disturbed.
