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

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%

Abiotic and biotic factors are what determine where an organism may live and how much a population can grow. For example, an organism needs water to be able to live and a population also needs water to be able to live as well. Without water, neither organism or population would be able to survive/grow.
