Question

During sexual reproduction, two gametes merge to create a zygote that is a genetic mix of its two parents. For each statement, indicate whether it is true or false for sexual reproduction. 50% of the genome of the zygote will come from each parent. Answer 1 Sexual reproduction produces greater genetic variability than asexual methods. Answer 2 50% of the chromosomes in the zygote will match the chromosomes found in one parent, and 50% will match those found in the other parent. Answer 3 The gametes must be produced by two different individuals. Answer 4 Plants always produce both eggs

Answer 1

Answer:

1. 50% of the genome comes from each parent because it is crucial otherwise if the ratio changes, the zygote may not form and if formed the fetus may have some other kind of chromosome number related syndromes etc.

2.  Sexual reproduction produces greater genetic variability than asexual methods. This is because of the process of crossing over during meiosis that exchange the segments of chromosome that is necessary for producing mutations and genetic variability.

3. 50% of chromosomes match with each parent because both of the parents contributed 23 chromosomes and exactly 50% of their genome.

4. The gametes must be produced by two different individuals cause that is the main purpose of sexual reproduction and give better survival like this to the forming next generation. Not to mention produces greater genetic variability among species.

5. Plants always produces both eggs because they are hermaphroditic in nature.

Answer 2

Answer:

Answer 1: True

Answer 2: True

Answer 3: True

Answer 4: False

Explanation:

1. 50% of the genome of the zygote will come from each parent is true because  in a zygote, 50% are from father and 50% of genome from mother.
2. Sexual reproduction produces greater genetic variability than asexual methods is true because of recombination and independent assortment during gamete formation in meiosis will produce genetic variation in gamete. When fusion of such gamete occurs. This produces create genetic diversity in sexual reproduction whereas in asexual reproduction, such recombination are not seen.
3. 50% of the chromosomes in the zygote will match the chromosomes found in one parent, and 50% will match those found in the other parent is true because 50% of the chromosomes are of maternal in nature where as 50% are paternal in nature in zygote.
4. The gametes must be produced by two different individuals is False because in case of monoecious plant and animals, make and female gamete are produced by same individual also.
