During sexual reproduction, two gametes merge to create a zygote that is a genetic mix of its two parents. For each statement, i
Elenna [48]

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.

13

Explanation:

We will divide the total number of the teachers (246) in the auditorium with the maximum number of seats per row (18) to determine how many rows are completely filled;

246/ 18  = 13.6667

We are only interested in rows that are completely filled which is the whole number;

= 13

What is conservation genetics?Question 82 options: conserving a species genome so that it is best adapted to the current environ
solong [7]

Answer:

a way to inform conservation efforts based on genetic information from species

Explanation:

Genetic studies in wildlife and captivity species provide significant information to understand aspects regarding the biology and ecology of species, especially endangered species. Many discoveries have been useful to solve several taxonomic issues, determine the risk of diseases, and explain reproductive problems, among other problems. What is even more important is that genetic knowledge helps to plan management programs and conservation. Together with other areas related to behavior and conservation, genetic knowledge provides the basis to carry out successful conservation strategies.
