Unit 3 List 3 DNA & Heredity TJB

Question 1

Cellular Division

Answer 1

A cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.

Question 2

Egg Cell

Answer 2

The female reproductive cell, or gamete

Question 3

Epigenetic

Answer 3

How cells control gene activity without changing the DNA sequence

Question 4

fertilization

Answer 4

The sperm from a male meets an ovum from a female and forms a zygote

Question 5

Genome

Answer 5

The haploid set of chromosomes in a gamete or microorganism, or in each cell of a multicellular organism.

Question 6

Inherited traits

Answer 6

The traits or characteristics that are transferred from parents to the offspring, genetically

Question 7

Multicellular organisms

Answer 7

Multicellular organisms are made of more than one cell and are complex organisms.

Question 8

sexual reproduction

Answer 8

The production of new organisms by the combination of genetic information of two individuals of different sexes.

Question 9

Sperm cell

Answer 9

The male Gamete

Question 10

autosomal

Answer 10

The gene in question is located on one of the numbered, or non-sex, chromosomes.

Question 11

Complete dominance

Answer 11

A form of dominance wherein the dominant allele completely masks the effect of the recessive allele in heterozygous conditions

Question 12

Dihybrid cross

Answer 12

Dihybrid cross is a cross between two individuals with two observed traits that are controlled by two distinct genes.

Question 13

F1 (first Filial)

Answer 13

The first generation of offspring from a monohybrid cross.

Question 14

F2 (second Filial)

Answer 14

The F2 generation is defined as the result of a cross between two F1 individuals.

Question 15

Genotype

Answer 15

The complete set of genes in an organism

Question 16

Genotypic ratio

Answer 16

The ratio depicting the different genotypes of the offspring from a test cross.

Question 17

Hardy-Wienburg

Answer 17

Aight honestly I have no idea what you want me to put here. I cant ask you cause ts four days late cuz I forgot about it with all my other bs. I don’t know if you actually read these tho so this can be a cool experiment.

Question 18

Hardy-Wienburg equilibrium

Answer 18

Allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences.

Question 19

Incomplete dominance

Answer 19

Incomplete dominance in genetics is an inheritance pattern where two alleles blend to create a new phenotype.

Question 20

Monohybrid cross

Answer 20

Monohybrid cross is a cross between two individuals that differ in only one observed trait.

Question 21

P (parental) generation

Answer 21

The p generation is the original pair of parents at the start of a genetic cross experiment.

Question 22

Phenotype

Answer 22

The set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

Question 23

Phenotypic ratio

Answer 23

The ratio of different phenotypes present in the offspring of a cross

Question 24

Polygenic inheritance

Answer 24

A characteristic, such as height or skin color, that is influenced by two or more genes.

Question 25

Population

Answer 25

All the organisms of the same group or species that live in a specific area and are capable of breeding among themselves.

Question 25

Ratio

Answer 25

The quantitative relation between two amounts showing the number of times one value contains or is contained within the other

Question 26

Variation

Answer 26

The differences between individuals of the same species, caused by genetic and environmental factors.
