Question is incomplete. Complete question has been attached.
Answer:
d. X
Explanation:
According to the given data, Tom is looking for five desirable traits in his hamsters. These traits are dark brown color, white bellies, long fur, black eyes and long tails. He should choose the male which can result in maximum number of the given traits.
We do not have any knowledge about the mode of inheritance of these traits ( dominant, recessive, multiple gene etc. ). So the decision should be eyeballed according to the phenotype present in the male. The male which has maximum number of desirable phenotypes should be mated with the female to increase the chances of bringing the desirable alleles together and thus getting the progeny with the same traits.
Out of the four given options Hamster W, Y and Z have 3 desirable traits whereas Hamster X has four desirable traits ( dark brown fur, white belly, long fur and long tail ). Hence, Tom should buy Hamster X in order to have best chance of breeding baby hamsters with most of the desirable traits.
Answer:
This question lacks options, however, it can be answered based on general understanding of the topic
The answer is SUBSTITUTION MUTATION
Explanation:
A mutation is any change that occurs in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. One type of mutation is SUBSTITUTION MUTATION, which is a mutation in which one or more nucleotide base is replaced by another in the sequence.
Nucleotide bases are read in a group of three called CODON. Each of these codons specify amino acid. Hence, if the nucleotide base sequence is altered during mutation, the amino acid sequence is altered likewise. In this case where the original amino acid sequence is: Met-Ala-Gln-Arg-Glu-Leu, the mutation affected the nucleotide bases coding for Arginine (Arg), hence changing it to Glycine (Gly).
This means that a base substitution mutation occured, replacing the amino acid Arginine with Glycine in the mutated sequence.
The choices can be found elsewhere and are as follows:
<span>A) They are all wind pollinated.
B) They are heterosporous.
C) They can reproduce asexually by producing gemmae.
D) They require water for reproduction.

The correct answer would be option D. Besides not having vascular tissue, they require water for reproduction. <span>Their flagellated sperm must swim through </span>water<span> to reach the egg. Hope this answers the question.</span>
