Answer: most sex-linked genes are on the X chromosomes because they are larger than Y chromosomes. Males are more likely than females to exhibit sex-linked traits
Explanation:
Males are more likely than females to display recessive traits because a single recessive gene on the X chromosome is often not matched by a Y chromosome allele and therefore expressed.
Answer:
The most likely explanation for the high rate of sympatric speciation that apparently existed among the cichlids of Lake Victoria in the past is sexual selection.
Explanation:
Divergent sexual and natural selection on the visual system has been confirmed earlier in sympatric, morphologically comparable sister species of Lake Victoria cichlids, but this seems not to reveal the exact morphological variations within them.
Cichlid fish reasonably describe the enormous inventory of standards of speciation and reproductive isolation without geographical or ecological separation.
Most of the recent observations have not confirmed the hypothesis, implying that sexual selection may be effective for the bursting cichlid speciation in the lake. Workroom practices have shown that reproductive isolation of three morphologically comparable species of rock-dwelling cichlid fish.

The answer would be peanuts, Which contain a total of 24 g of carbs.
Sorry if i'm wrong! i just went on a mini reasearch spree :3
The question is incomplete as it does not have the options which are
A. no change since both amino acids are negatively charged
B. modest change because both amino acids carry a charge
C. modest change because both are about the same size
D. severe change because the amino acids are oppositely charged, one negative one positive
E. severe change because replacing the aspartic acid would severely alter the confirmation of the protein and the protein would probably be degraded
Answer:
Option-E
Explanation:
The helix-turn-helix is the DNA binding motif which binds with the DNA binding domain and controls the gene expression. The helix-turn-helix binds the DNA as a dimer.
If a mutation in the gene which codes for the motif changes one amino acid that is glutamic acid to the proline it will alter the conformation of the protein.
The reason for this is that proline, when is present in the peptide, does not have the hydrogen ions to donate as a result of which it does not form the helix structure and thus helix structure will not be stabilized with this and the protein will be degraded.
Thus, Option-E is correct.
