Answer:
"The combination of sex chromosomes received from parents " .
Explanation:
Sex determination : The process by which sex of a child is determined .
Parental generation :
Mother Father
XX XY (sex chromosomes )
X,X X,Y (gametes )
First filial generation :
X Y
X XX XY
X XX XY
If XX is formed then it is girl and if XY is formed then it is boy .
Conclusion :
- we concluded that there is 50-50 percent chance of boy or a girl .
- Sex of a child is determined by father because father produce different gametes .
Phototropism plants the most
Answer : Binary Fission which grows exponentially.
Explanation : Binary fission actually means binary - consisting two and fission - cleavage into halves. It is one of the modes of asexual reproduction.
This type of fission is majorly observed in the asexual reproduction in prokaryotes. It is rarely seen in some some single-celled Eukaryotes like Amoeba and Paramecium.
Also, In binary fission there is DNA replication and segregation which occurs simultaneously.
This increases the graph exponentially as the growth gets faster and faster with the passing period of time.
A reference image of binary fission is attached in the answer.
Answer:
There may be a decrease in cellular respiration
Explanation:
Answer:
Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.
The disadvantage from not having the trait normally arises only after the reproductive stage of the individual's lifecycle is mostly over. This is a special case of "no strong pressure", because evolution selects genes, not the organism. In other words the beneficial mutation does not alter the reproductive fitness.
