Please help!! <br>I WILL MARK BRAINLIEST!!!!​
kicyunya [14]

Answer:

1.A

2.C

3.D

4.C

5.A

Explanation:

1.There are some characteristics that are inherited from your parents, shape of blood cells is one of them. In sexual reproduction, offspring are formed when sperm of male combine with egg of female organism.Therefore, some characteristics comes from male organism and some from female organism. In sexual reproduction, diploid organism is formed because half of genes comes from male and half comes from female.

2.Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents

3.A monk, Mendel discovered the basic principles of heredity through experiments in his monastery's garden. His experiments showed that the inheritance of certain traits in pea plants follows particular patterns, subsequently becoming the foundation of modern genetics and leading to the study of heredit

4.Mendel made sure to study 30,00 pea plants when he presented his data to the community. Another example is when Mendel painstakingly removed all of the immature anthers from the plant’s flowers before the cross.Mendel used seven pea plant traits in his experiments which include flower color (purple or white), flower position (axil or terminal), stem length (long or short), seed shape (round or wrinkled), seed color (yellow or green), pod shape (inflated or constricted), and pod color (yellow or green).

5.A pea plant could have a copy of the height gene that coded for "tall" and a copy of the same gene that coded for "short." But the tall allele is "dominant," meaning that a tall-short allele combination would result in a tall plant
