Answer:Any organism is a by-product of both its genetic makeup and the environment. ... In biology, a gene is a section of DNA that encodes a trait. ... An autosomal dominant allele will always be preferentially expressed over a recessive allele. ... Whilst a phenotype is influenced the genotype, genotype does not ...
Explanation:
<u>Answer:</u>
<em>Cluster of neurons cell bodies in the thalamus is called nucleus.
</em>
<u>Explanation:</u>
Nuclei are present all various points in the central nervous system and are connected to each other through various tracts. Thalamus is a part of the brain and contains different type of nuclei.
<em>They are relay nuclei, association thalami nuclei and non-specific nuclei.
</em>
Association thalami nuclei receives the highest input from the cerebral cortex. Non-specific nuclei plays a significant role in regulating sleep and wake cycles.
The first life form found on earth were mostly bacteria. "For the next 1.3 billion years (3.8 to 2.5 billion years ago), the Archean Period, first life began to appear and the world's landmasses began to form. Earth's initial life forms were bacteria, which could survive in the highly toxic atmosphere that existed during this time."

Explanation:
Answer:
25%
Explanation:
<u>Genotypes and phenotypes:</u>
- SS = straight hair
- CC= curly hair
- SC = wavy hair
- AA or A0= type A blood
- BB or B0= type B blood
- AB = type AB blood
- 00 = type 0 blood
A man with straight hair and A blood has the genotype SS AA or SS A0.
A woman with wavy hair and B blood has the genotype SC BB or SC B0.
Their first child has straight hair and O blood: SS 00
Because the child has type 0 blood, both parents must have a 0 allele, so their genotypes are SS A0 and SC B0.
<u>If their second child is a boy with straight hair, what is the probability that he has A blood?</u>
The hair and blood type genes are independent, so the hair phenotype of the child is irrelevant to determine the probability of him having A blood.
The parental cross for blood type is A0 x B0.
If you do a Punnett Square, you'll get the following offspring:
25% AB, 25% B0, 25% A0 and 25% 00.
The answer is the child has a probability of 25% of having A blood.
