chromosome

A "threadlike" structure in the nucleus, composed of DNA

hybrid

A cross between parents which has different phenotypes for a specific trait

recessive

A gene or trait which is masked when a dominant allele is present

trait

A genetic characteristic of the individual

DNA

A giant molecule consisting of the sugar deoxyribose, phosphates and nitrogen bases

which differ in only one trait

A monohybrid cross is made between plants:

homozygous

A pair of genes in an organism which are identical in the way they influence a trait

gene

A portion of DNA which codes a specific hereditary trait

gamete

A reproductive cell produced by the male or female parent

allele

Alternative forms for a specific gene.(either dominant or recessive)

true-breeding

An organism which is homozygous

false

Each P1 parent of a monohybrid cross has completely identical genes.

F1 generation

First filial generation; the first generation from a given cross

false

Gregor Mendel was a respected, professional scientist who introduced the science of biology.

dominant

In a pair of genes, one may prevent the allele from being expressed

heterozygous

Refers to a pair of genes for a specific trait in an organism which are different

F2 generation

Second filial generation

monohybrid

The breeding of two organisms which differ in a single trait

dominant trait

The characteristic which resulted from a monohybrid cross is the

genotype

The genes present in an organism

self-fertilization

The organism brings the two genetically identical gametes together to offspring

phenotype

The outward appearance of the organism which is the product of gene action

P1 generation

The parental generation for a given cross

F1 or hybrid

The seeds collected from the first generation monohybrids are called:

tetrad

The two pairs of chromatids of the homologous pair of chromosomes comes together

pollination

Transfer of pollen in plants to the stigma which contains the female gamete

deviation

Variation from the predicted values

none of the above

What can be expected for the recessive trait of monohybrids from the F2 generation?

to control the crossing of the traits

Why did Mendel prevent his plants from self-pollinating?

true

A reptile has never been observed to give birth to a bird

kind

According to scripture, all known occurrences in the laboratory of the Earth have shown that each kind of organism is limited to reproducing a similar

remove the stamen

In addition to covering each pea plant to prevent pollination from other pea plants in his garden, what did Mendel do to prevent self-pollination?

Genesis 1:24: Then God said, "Let the earth bring forth the living creature according to its kind: cattle and creeping thing and beast of the earth, each according to its kind"; and it was so. Genesis 1:12: And the earth brought forth grass, the herb that yields seed according to its kind, and the tree that yields fruit, whose seed is in itself according to its kind. And God saw that it was good.

Which scriptures describe a biologic law of reproduction for which no exception has ever been documented?
