A cross between a yellow snake and a blue snake produces offspring that are all green. What type of inheritance is this?
Answer:
co dominance
Explanation:
codominance is a type of inheritance in which both allels are dominat over each other and the two allels are expressed to an equal degree in an offspring,that is why the cross between yellow and blue snake give another green colour offsprings in stead of giving all blue or all yellow offsprings depending on which allel is dominant.
as example we can take human blood group AB which is inherited from blood group A and B and both allel A and B are dominant over each other.

Rabbits can exhibit a number of colors in their coats: black, white, tan, brown, red, and grey. A disease randomly kills off most of the population and leaves only black and grey rabbits. Future generations are only black or grey. What is the term used to describe this
phenomenon? (1 point)
1. artificial selection
2. genetic drift
3. natural selection
4. genetic modification
please hurry and I will mark brainliest!
Answer:
2. Genetic Drift
Explanation:
Because it's simply by chance not on purpose or because their stronger.
Term used to describe the phenomenone where only black and grey rabbits survive and rest are killed randoml is called Genetic Drift..
What is genetic drift?As a result of a chance or random event, the frequency of an allele in a population drifts over time compared to the frequency of the other alleles. this is termed as genetic drift. Here, the rabbits with other coat colors were randomly killed off due to the disease which increased the frequency of the black and grey coat allele and hence the population drifts from multicolored coats to only black and grey colored rabbit coats.Hence the correct option here will be 2. Genetic Drift
other options are incorrect because:
Artificial selection is inducing the desired traits artifically which is not possible because the disease was a random event and not induced by humans.Natural selection is the survival of the fittest of the alleles and elimination of less fitter alleles. here it is not mentioned whether Black and grey coats were more fitter to survive than other coatsGenetic modification is a human made procedure and did not occur here.learn more about Genetic Drift here:

Given what we know, we can confirm that the animals listed that are not a part of the anthropoids are the Eosimiidae.
Why are they not anthropoids?The Eosimiidae' are a species of now-extinct primates that very closely resemble the anthropoid family. They were once linked to the anthropoids and thought to belong to this group due to their very similar traits and behaviors, over time, however, it was discovered that they did not in fact belong to this grouping.
Therefore, we can confirm that the animals listed that are not a part of the anthropoids are the Eosimiidae.

Answer:
1. is the wave crest
2. is the wave trough
3. is the amplitude
4. is the wave length
Explanation:
1. crest point on a wave is the maximum value of upward displacement within a cycle.
2. A trough is the opposite of a crest, so the minimum or lowest point in a cycle.
3. distance between two successive crests (or troughs) is the length of the wave or wavelength.
4. amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.

Why is mass selection considered a form of selective breeding?
Mass selection is considered a form of selective breeding because it includes selection of individuals from a large group organisms.
What is mass selection?Mass selection is defined as a type of selective breeding in which two species are chosed and breeded with one another. This process is used to get the desired characteristic organism.

Which one below will end up being expressed in the protein?
a) Intron
b) Exon
c) Transcription factor
d) Terminator
e) Promoter
Exons are the DNA fragments that get to be transcripted and translated into proteins. Option b) Exons end up being expressed in the protein.
What are introns and exons?Even though more than 70% of the DNA is related to genes, just a part of the genes is translated to proteins. Most genes have DNA segments that are not transcripted or translated intercalated with segments that are translated.
Introns are non-encoding sequences that produce interruptions in a eukaryotic gene. Exons are the encoding sequences. Exons are the nucleotidic sequences that do codify proteins.Most of the eukaryotic, multicellular genes contain introns in their sequences, intercalated with exons.
Introns are transcripted to mRNA molecules and get excised before translation by a specific mechanism. This occurs before the mRNA leaves the nucleus. The introns are excised and the exons must splice to form a unique molecule. This process is known as splicing.
Exonic sequences are the fragments that are transcripted and translated into proteins.
The correct option is b). Exons end up being expressed in the protein
