Answer:
Explanation:
The observed frequency of the double crossovers (DCOs) is 20/1000, or 0.02. If there is no interference then this will be the same as the expected, which is just the product of the single crossover frequencies, that is, SCO frequency (a-b) x SCO freq. (b-c) = 0.02.
(a) Any combination of map distances whose product (a-b) x (b-c) = 0.02 is possible. However, three are most likely:
a 20 mu b 10 mu c
a 10 mu b 20 mu c
a 14.14 mu b 14.14 mu c
(b) The distances would be exactly the same.
(c) The expected number of DCO progeny would be 17.
<h2>Incomplete dominance & Co dominance</h2>
Explanation:
- Twist- The mutant allele is prevailing to its relating wild-type allele.
- forked-the mutant allele is predominant to its relating wild-type allele.
- Pale-The mutant allele is neither prevailing nor totally passive to its comparing wild-type allele.
- Mendel's outcomes were earth shattering halfway in light of the fact that they repudiated the (at that point well known) thought that guardians' attributes were for all time mixed in their posterity. At times, the phenotype of a heterozygous living being can really be a mix between the phenotypes of its homozygous guardians.
- Closely identified with inadequate predominance is codominance, in which the two alleles are all the while communicated in the heterozygote.
- Hence, the twist mutations are codominant allels at same locus.
Answer: The x-axis has mother bird and the y-axis has chicks
Explanation:
The researchers studying the relationship between the number of eggs which is laid by the birds and the number of chicks which is surviving at the end of the year.
The researchers will make a graph between these two factors. One is eggs laid and the number of chicks that survived till the year last.
This will help to known of the proportion of the chicks which survived on an average.
This is corect but METHANE IS THE NUMBER ONE REASON WE HAVE GLOBAL WARMING
