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: 25% of the offsprings will be heterozygous for both traits
Explanation: A cross between BbFf and bbff will yield 16 offsprings with four different possible genotypes: BbFf, Bbff, bbFf, and bbff. Only BbFf is the genotype that is heterozygous for both traits, and there are four offsprings with BbFf genotype.
Therefore the percentage of the offsprings that are heterozygous for both traits is 4/16 x 100 = 25%
See the punnett square for the details of the dibybrid cross
Answer:
genetic drift
Explanation:
Genetic drift is a change in the frequency of an allele within a population over time. There are no environmental influences that cause genetic drift to occur.
