Genetics. Investigation 9-2. Quick Review. The traits in a population of walkingsticks change over the course of several generations. Green Brown Green-brown How can that kind of change happen?. Inheritance. Passing genetic information from one generation to the next
Passing genetic information from one generation to the next
(why offspring grow up pretty much looking like their parents)
(alleles aren’t really dark-its used to represent the location of the alleles on the chromosomes)
Identify the two alleles for each feature as dominant or recessive
Leg length –
(draw the legs on the larkey)
The offspring of organisms often grow up to look like one or both of their parents. This is because offspring inherit information from their parents that directs their development.
The inherited information is located in the _____________ of every cell in the organism. The information is coded in the huge ______________ molecule. The huge molecules are coiled into compact hot dog–shaped structures called ______________. ________________ are always present in almost identical pairs. Locations on chromosomes that affect features of organisms are called ______________. A gene is composed of _____________.
An organism’s unique combination of genes is its . The traits produced
by an organism’s genes is its _____________. Alleles that have more influence in
determining traits are _____________alleles. Alleles that have less influence in determining
traits are ______________alleles.
