UNIT 3 List 3 DNA and heredity Flashcards
What is cellular division?
process of making new cells/ cells dividing to make new cells
what is a egg cell
female cell
what is epigenetic
study of how cells control gene activity without changing the DNA sequence
what is fertilization
The process by which two gametes fuse to become a zygote, which develops into a new organism
what is genome
ll the genetic information of an \organism
what is inherited traits
particular genetically determined charac- teristic or quality that distinguishes somebody
what is multicellular organism
organism composed of many cells
what is sexual reproduction
production of new organisms by the combination of genetic information of two individuals of different sexes
what is sperm cell
small, compact cell, highly specialized for the task of fertilizing an egg.
what is autosomal
pecific gene is not on a sex chromosome and is a numbered chromosome
what is complete dominaince
one allele is fully dominant over the other
what is dihybrid cross
breeding experiment between two organisms which are identical hybrids for two trait
what is F1 First filial
first generation of offspring
what is hardy wienberg
genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
what is F2 second filial
group of people born as a result of inbreeding and interbreeding among members of the same family
what is genotypic
what is genotypic
what is hardy weinberg
genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
what is incomplete dominance
genetic phenomenon in which the distinct gene products from the two codominant alleles in a heterozygote blend to form a phenotype intermediate between those of the two homozygotes
what is monohybrid cross
cross involving just one gene
what is P (Parental) generation
first in any genetic cross pollination experiment
what is phenotypic ratio
ratio of possible outcomes for an organism based on physical appearance
what is polygenic inherience
characteristic, such as height or skin color, that is influenced by two or more genes.
what is population
whole number of people or inhabitants
what is ratio
comparison of two or more numbers and it indicates the numbers’ sizes
