I am pretty sure the answer is D (combination)
Answer: The correct answer is option a.
Explanation:
Prezygotic isolation is a mechanism by which mating and fertilization is prevented. Thus, it prevents the formation of a zygote.
It can be achieved by various reasons such as temporal differences (difference in mating seasons), habitat isolation, behavioural differences (different mating rituals such as different dance patterns, voice calls, et cetera), mechanical isolation, et cetera.
Thus, different breeding calls prevent the species to interbreed with each which ultimately prevent the formation of zygote formation.
Hence, it is a type of prezygotic isolation.
Answer:
or 0.0079.
Explanation:
Joyce is planting tulips in her garden.
Number of red (R) bulbs = 5
Number of white (W) bulbs = 5
Total number of ways to plant 10 bulbs in one row is


Cancel out common factors.

It is given that she randomly plants the bulbs so that all 5 red bulbs are next to each other and all 5 white bulbs are next to each other.
Required outcomes are
RRRRRWWWWW and WWWWWRRRRR

Formula for probability:




Therefore the required probability is
or 0.0079.
Answer: True Because the segregation of alleles into gametes can be influenced by gene linkage
.75. 75% A because is is a dominant gene. a is 25% because it is recessive, and is mostly overcome by a dominant gene.
