They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.
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%
