Traits are
Is a single form of characters
Is an inherited characteristic
A pair of genes that occupy a specific location on a particular chromosome & control the same trait
Is a double form of character
A character is
An inherited characteristic such as having a flower
Asingle form of character, eg. Having a purple flower
A pair of genes that occupy a specific location on a particular chromosome and control the same traits.
Genes
The passing of genetic traits from parents to offspring
Is a portion of DNA that determines a certain trait
Is an alternative form of a single gene
Allele
Is an alternative form of a single gene
A portion of DNA that determines a certain trait
When a male gamete from one flower combines with the female gamete inside the ovary of another flower.
The separation of allelic genes that typically occurs during meiosis is?
(a)
From where does an organism get its unique characteristics?
From the traits
From allele
From genetics
During meiosis
True or False: True breeding is when the parent are both dominant and the offspring is dominant too; In other words, both parents are homozygous(Dominant).
True
False

Pea plants are usually produced by?
Self-fertilization
Cross-pollination
Self fertilization
Occures when a male gamete within a flower combines with the female gamete in the same flower.
Is the transfer of pollen grains from the anther of flower to the stigma of the female portion of another flower
Cross-pollination
Is the transfer of pollen grains from the anther of flower to the stigma of the female portion of another flower
Is when the male gamete from one flower combines with the female gamete inside the ovary of another flower.
Why did gregor mendel used cross-pollination to study inheritance?
The point is to test how different traits are inherited, which requires different plants with different traits
The point is to see how many flowers will be planted

First generation (F1)
Parent generation (pure breeding)
Second generation (F2)
C is?
Second generation (F2)
First generation (F1)

A
B
C
