What is fitness in biology

1 answer:

5 0

Fitness is the quantitative representation of natural and sexual selection within evolutionary biology. It can be defined either with respect to a genotype or to a phenotype in a given environment.

I hope this helps, if you need any more help on science please ask me, if it is right please give me brainest if not tell me that it wrong

Have a nice day!

natali 33 [55]

Answer:

global temperature increasing as CO2 concentration increases

Explanation:

Global warming is the progressive increase in the temperature of the earth's atmosphere. Global warming is caused by an increase in the concentration of greenhouse gases e.g CO2, chlorofluorocarbons etc. These greenhouse gases, in which carbondioxide is an important example, are capable of trapping heat in order to keep the earth warm.

Howeever, as the concentration of CO2 and other greenhouse gases increase in the atmosphere, the earth's atmospheric temperature also increases above normal, causing Global warming.

In this case, the science teacher's graph will show that global temperature is increasing as CO2 concentration increases.

3.6 In mice, the allele C for colored fur is dominant over the allele c for white fur, and the allele V for normal behavior is d

KengaRu [80]

Answer:

a) Parents Genotype should be (CC,Vv) and (cc,VV).

b) The genotypes of the parents are (Cc,Vv) and (Cc,Vv).

c) The genotypes of the parents are (Cc,Vv) and (cc,vv).

Explanation:

Mating has occured between a normal colored mice whose genotype is C_,V_ and normal white mice with genotype cc,V_. The offsprings are as follows :

1) normal mice produced 29 colored

2) 10 colored, waltzing progeny.

Thus all offspring are normal. The genotype of the first parent should therefore be CC. Waltzing trait is produced. The V gene should therefore be heterozygous in both traits.

Hence The parent genotypes should be<u> (CC,Vv) and (cc,CV).</u>

In this case the approximate ratio in which the descendants are produced is 9:3:3:1. Hence genotypes of the parents are <u>(Cc,Vv) and (Cc,Vv). </u>

In this case the approximate ratio in which the offsprings are produced is 1:1:1. The genotypes of the parents are <u>(Cc,Vv) and (cc,vv). </u>
