Answer:Mutations in these genes can produce new or altered traits, resulting in heritable differences (genetic variation) between organisms. ... Evolution occurs when these heritable differences become more common or rare in a population, either non-randomly through natural selection or randomly through genetic drift.
Explanation:
Answer: on number 4 ints fact
Explanation:
Answer: When genes found on different chromosomes, said to be not linked.
When genes seen close together on the same chromosomes said to be linked.
Explanation:
(a)
According to Mendel’s law of independent assortment, when genes located more than 50 map units and found on different chromosomes as far apart on the same chromosome so they divide independently and obviously said as not linked.
(b)
It is found that when genes located and seen tightly close together on the same chromosome, known to called as Linked which means that alleles or genes look close together on the same chromosome can be inherited afterwards as a unit frequently than not. For instance, when two genes are linked and become tightly close together by using data from genetic crosses lead to calculate recombination frequency as well.
Similarly, when we finding recombination frequencies for more than one gene pairs, can make linkage maps among them that finally show the relative distance between them.
I'm almost certain that the answer would be X and Y
Hoped this helped!
