Your answer is D. 32

If it has 5 pairs of chromosomes, it could produce 2^5 or 32 unique chromosomes. The number of different gametes is determined by counting the number of heterozygous chromosomes and raising 2 to this power. So, if all the homologous are exactly the same, there would only be 1 possible type of chromosome.

An organism with NO heterozygous chromosomes, like BB or AAbbCCDDeeFF can produce 2^0 or 1 type of gamete- B or AbCDeF, respectively. An organism with the genotype AaBBccDdee has 2 pairs of hetrerozygous chromosomes (the As and the Ds), so the number of different gametes is 2^2 or 4. So, an organism with 5 pairs of chromosomes, AaBbCcDdEe, could produce 2^5 or 32 gametes: aBCDE, AbCDE, ABcDE, etc.

Give an example of how you could determine whether or not a trait was displaying incomplete dominance. What would you do? What w

nexus9112 [7]

Answer:

When one parent with straight hair and one with curly hair have a child with wavy hair, that's an example of incomplete dominance. Eye color is often cited as an example of incomplete dominance.

Explanation:

Incomplete dominance is when a dominant allele, or form of a gene, does not completely mask the effects of a recessive allele, and the organism's resulting physical appearance shows a blending of both alleles. It is also called semi-dominance or partial dominance. One example is shown in roses

Which of the following is true of translation?

shutvik [7]

Answer:

B) it requires only transfer RNA (tRNA) and ribosomes.

Explanation:

After the transcription of DNA to RNA in nucleus of cell, the ribosomes synthesis protein and this process is known as the Translation. For the translation process to occur, it requires transfer RNA (tRNA) and ribosomes.

The translation process is also known as cell expression. The ribosomes help in translation by inducing transfer of tRNA sequence of anticodon to codon of mRNA.
