Answer:
20:Yes,individual #1 is XBXb,as the mother passes on the recessive Xb to her sons. The son individual #2 in generation 2 is affected by the recessive gene which he can only inherit from his mother.
21:mother
22:Sex-linked are Gene's carried on the sex Gene's chromosomal pair 23 whereas autosomal can be carried by any of the other 22 chromosomal pairs.
23:one
24:Yes
100% shaded,all 3 individuals
Homozygous dominant(HH) crossed with homozygous recessive (hh) yields a probability of 100% Hh.
The codons that code for alanine in a potato beetle are the same as those that code for alanine in mackerel and humans. This evidence best supports the idea that -(D) different species share components of the genetic code
Explanation:
Evaluating the other options given
A.humans and fish evolved from insects
-This option is incorrect as human and fish did not have a common ancestors.
B.
different species synthesize the same proteins
:No this statement also is not the correct option
C.
insects, fish, and humans express the same genes-The expressed genes cannot be same for different species
Hence the correct answer is
The codons that code for alanine in a potato beetle are the same as those that code for alanine in mackerel and humans. This evidence best supports the idea that -(D) different species share components of the genetic code(As the genetic code is said to be universal
Answer:
