Answer:
b
Explanation:
it must survive to reproduce
Answer:
75years
Explanation:
Let the Father's age be represented by 2x
Let the Son's age be represented by x
Five years ago;
Man's age will be = 2x - 5
Son's age will be = x - 5
If the ratio of their ages five years ago was 9:4, then;
2x - 5/x-5 = 9/4
4(2x - 5) = 9(x - 5)
8x - 20 = 9x - 45
- Collect like terms
-20 + 45 = 9x - 8x
25 = x
Hence, the son's age = 25 years
If x = 25, the father's age (2x) will be 2 × 25 = 50years
The sum of their ages will be = 25years + 50years = 75years

Traits included physical features such as flower color. Today, these factors are called <u>alleles</u>. Mendel developed the hypothesis that some factors could be dominant, while others were <u>recessive</u>. According to his theory, a dominant factor is expressed when <u>only one factor is presen</u>t in the offspring. On the other hand, a <u>recessive</u> factor expresses its <u>phenotype</u> when <u>both factors are present</u> in the offspring. Today, the term<u> genotype </u>refers to the combination of factors possessed by an organism.
- alleles
- recessive
- only one factor is present
- recessive
- phenotype
- both factors are present
- genotype
