Answer:
i am not sure of this answer because there are a lot of answers for this question but what i came up to is that there might be a large population of different predators that hunts down this bird species
Explanation that means that the more the predator feeds on this bird species ( and other species too , unless this species is the predator's main source of food) the more the population of predators increase and that means that the predators will keep feeding on this bird species until it completely wipes out this bird species or the bird species migrates to an area where there are less predators.
(hope this help + i answered according to how i understood the question)
Since it is already answered, I am just coming to get the points (someone just stole mine recently lol). I hope you don't mind, and have a great day!
Answer:
The probability that their first child will have long fingers is 20%
Explanation:
<u>Available data</u>:
- long fingers are inherited with 80% penetrance
- L represents the dominant allele for short fingers
- l represents the recessive allele for long fingers
Cross) Two people heterozygous for long fingers mate
Ll x Ll
Gametes) 1/2 L 1/2l 1/2L 1/2l
Punnet Square)
L l
L LL Ll
l Ll ll
F1) 25% or 1/4 LL
50% or 1/2 Ll
25% or 1/4 ll
Long fingers are inherited with 80% penetrance, which means that 80% is the proportion of the population that expresses the phenotype long fingers. Hence, the probability that the first child in this cross will have long fingers is:
100% ------- 80%
25% -------- X = 20%
