<u>Answer:</u>
The process of reproducing offspring from female eggs without any male involvement.
<u>Advantages</u>
1- Rapid production of numerous offspring and there is need of male gametes.
2- Require less amount of time and energy
3- Offspring are the exact copies of the parents and are called clones as they are similar morphologically and genetically.
<u>Disadvantages</u>
1- There is no genetic variability.
2- No new genetic combinations which can be a threat for their survival during population selection.
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%
