Tags and Description

20 Terms

1

Codominance

________ occurs when two dominant alleles are equally expressed.

New cards
2

Polygenic Inheritance

________ occurs when a trait is governed by two or more sets of alleles, i.e., AaBbCc.

New cards
3

Pleiotropy

________ occurs when a single mutant gene affects two or more distinct traits.

New cards
4

Modern genetics

________ has expanded the range of Mendelian genetics.

New cards
5

X-Linked Inheritance

______________ refers to genes that are located on the x chromosome but have nothing to do with gender.

New cards
6

Incomplete Dominance

________ occurs when the heterozygous phenotype is intermediate between homozygous dominant and recessive phenotypes.

New cards
7

Multiple alleles

There are several variations of Mendelian genetics which include: ________, Codominance, Incomplete Dominance, Pleiotropy, Polygenetic Inheritance, and X- Linked Inheritance.

New cards
8

There are several variations of Mendelian genetics which include

Multiple alleles, Codominance, Incomplete Dominance, Pleiotropy, Polygenetic Inheritance, and X-Linked Inheritance

New cards
9

There are three possible allele combinations

IA (A antigen is on the red blood cells), IB (B antigen is on the red blood cells), and i (there are neither A nor B antigens on the red blood cells)

New cards
10

Some examples include Cystic Fibrosis and Sickle Cell

  • severe anemia, poor circulation, pain, high fever, spleen damage, paralysis

New cards
11

The three possible allele combinations are:

IA (A antigen is on the red blood cells), IB (B antigen is on the red blood cells), and i (there are neither A nor B antigens on the red blood cells).

New cards
12

Hemophilia

___________ causes internal bleeding.

New cards
13

Muscle Dystrophy

____________ is the wasting away of muscles

New cards
14

Mendelian genetics

______________ is "the study of the pattern of segregation of phenotypes under the control of genetic loci taken one at a time.

New cards
15

Multiple alleles

________________ describes how several alleles for a given trait exist in a population.

New cards
16

A phenotype

For the _____________, the genotype can be IAIA or IBi.

New cards
17

B phenotype

For the _______________, the genotype can be either be IBIB or IBi.

New cards
18

AB phenotype

For the _____________________, the genotype can only be IAIB.

New cards
19

O phenotype

For the ________________________, the genotype can only be ii.

New cards
20

Loci

________ is "a plural of the word "locus" and "locus" is the position of a chromosome where a particular genetic trait presides." Sometimes used to describe multiple genes that affect the same function."
