Answer:
As the generations are increasing or gets much over time, we have a more likelihood of seeing a response to natural selections as the favourable alleles are going to be moved from one generation to the next while those that are not favourable would be eliminated over generations.
If the new host gives allowance for early reproduction and ease of access then the generations each year would rise.
Answer:
Option B
Explanation:
ALL options are as follows -
a. teosinte and maize can produce fertile hybrids.
b. teosinte and maize have similar chromosomes.
c. Both Teosinte and maize have naked, soft kernel.
d. Teosinte and maize can produce fertile hybrids
Solution
Beadle started working on maize genetics since 1962 after joining graduate school at Cornell University.
During his research he found that the chromosomes of teosinte and maize possess higher similarity and also show signs of intercross ability of the two species and hence confirmed that wild teosinte is an ancestor of domesticated maize.
He later concluded that there are only 4 to 5 genes that make these two species different from each other rest all is similar.
Option B is correct
Answer:
A functional group changes the structure of a compound but does not alter its chemical properties
D. DD = 0.0225; Dd = 0.1275; dd = 0.7225
The value of Dd is different in question.
<u>Explanation:</u>
Given -
Dark colored = DD, Dd
light colored = dd
Frequency of allele D = 0.15
Frequency of allele d = 0.85
Hardy-Weinberg equilibrium is applied.
DD = 0.15 X 0.15 = 0.0225
Dd = 0.15 X 0.85 = 0.1275
dd = 0.85 X 0.85 = 0.7225
Therefore, DD = 0.0225; Dd = 0.1275; dd = 0.7225
