Copy of CK12 3.2 Mendel's First Set of Experiments and Weblink (2/1/2024) - Elizabeth Stevens | Biblioteka

1

What were the first pea plants traits studied by Mendel?

Shape and smell

Taste and size

Seed shape and flower color

Height and color

1

What does the 'P' in P generation stand for in Mendel's experiments?

Pea

Plant

Primary

Parent

1

What method did Mendel use to cross different pea plants?

Germination

Fertilization

Cross-pollination

Hybridization

1

What were the flower colors Mendel used in his experiments?

Purple and White

Red and Blue

Pink and Orange

White and Yellow

1

According to Mendel's experiment, what color were the flowers in the first generation?

Purple

Purple and white

White

1

After self-pollination of the F1 generation plants, what color were some of the F2 generation flowers?

50% White

50% Purple

25 % White

25% Purple

1

What did Mendel assume produces white and purple flowers respectively?

Environmental conditions

Different forms of genes

Inherited factors

Random chance

1

What surprised Mendel when he allowed the F1 generation to self-pollinate?

Some F2 generation plants had white flowers

Only F1 generation could self-pollinate

All F2 generation plants were purple

F1 generation plants morphed into F2

1

Match the generational Mendelian names for his flowers with tradition family structures.

What is Mendel's Law of Segregation?

Dominant traits never pass to offspring

There is only one factor controlling a given characteristic which dominates all other factors of inheritance

There are two factors controlling a given characteristic, one of which dominates the other, and these factors separate and go to different gametes when a parent reproduces.

Traits never disappear in offspring

1

Which observation did Mendel make about the 'disappeared' characteristics in the F1 plants?

They reappeared in the F3 generation

They reappeared in the F2 plants

They varied in the F2 plants

They disappeared forever

1

What percentage of traits did Mendel find in the F2 plants for each experiment?

25 percent one trait, 75 percent the other

100 percent one trait, 0 percent the other

75 percent one trait, 25 percent the other

50 percent one trait, 50 percent the other

1

According to Mendel's Law of Segregation, what happens to factors during reproduction?

They disappear

They stay together

They go to different gametes

They combine in new ways

Mendel discovered that the traits we inherit, like eye color or height, are determined by something he called genes. He found that each parent has a pair of genes for each trait in every cell. When two parents have a baby, the baby gets one gene for a trait from each parent. Each gene can be a dominant or a recessive type. When the parents' genes combine to make a baby, they mix together randomly, so it's like flipping a coin to see which gene the baby gets for each trait. How is this concept presented on the webpage: Sequence order below

Each parent has a gene pair in each cell for each trait studied. The F1 from a cross of two pure lines contains one allele for the dominant phenotype and one for the recessive phenotype. These two alleles comprise the gene pair.
Gametes unite at random and irrespective of the other gene pairs involved
One member of the gene pair segregates into a gamete, thus each gamete only carries one member of the gene pair.
The hereditary determinants are of a particulate nature. These determinants are called genes.
