what is a phenotype

-a persons measurable or observable trait** finish

2

what is a genotype

-a genetic makeup of an individual;

3

a phenotype is

-a physical trait

4

which parent contributes the chromosome that determine the gender of the child

-a fathers chromosomes determine the gender of sons and daughters

5

if two individuals were heterozygous for freckles which is the dom trait what % of their progeny would have freckles

- 75%

6

an organisms ________determines their _____

-genotype ; phenotype

7

a mutation in DNA coding region of a protein can cause

- all of the above; different amino acids; no change; change the 3d shape; altered bonding between amino acids

8

what is the possible outcome of a mutation in terms of protein function

-beneficial; detrimental; neutral; all of the above

9

a human male has how many pairs of homologous chromosomes

-22

10

sister chromatids are separated during __

- meiosis 2

11

what is the principle of independent assortment

- the principle wherein alleles of maternal and paternal genes are aligned in the cell during meiosis and separated independently of one another

12

which represents a cross between 2 individuals heterozygous for a single trait

-Aa x Aa

13

which describes a genotype heterozygous for a single trait

-Aa

14

in a cross between an individual with huntington disease and an unaffected individual what are the chances their progeny will have the disease considering that it is a dominant trait

-50%

15

a phenotypically normal woman marries a man with wilson disease an autosomal recessive disorder. they have a snow has wilson disease if you need two copies pf the recessive allele to be affected and the mother doesn't have the disease

-the woman must have been a carrier of one recessive allele and one normal allele

16

two normal individual have a child who has cystic fibrosis an autosomal recessive disease what wrest he chances of this happening (punnet square)

- 1:4 chance

17

two people with huntington disease an autosomal dominant disorder have a son what are the chances he will get the disease (punnet)

-3:4 chance

18

in a cross between two heterozygous parents for two genes what is the chance that any progeny will be homozygous recessive for both traits?

-1:16

19

a man with AB blood type marries a heterozygous woman with blood type A they have children what percentage of their offspring would have blood type O

-
0%

20

multifactorial inheritance includes what factors to multiple genes interacting

21

aneuploidy is the result of

-nondisjunction

22

a group of cells performing a similar function is described as

-tissue

23

a group of tissues working together perform the complex functions of

-an organ

24

an organ is composed of

-a least two specialized tissues

25

in somatic cell nuclear transfer

-a diploid nucleus is inserted in to a enucleated stem cell

26

embryonic stem cells are harvested from the inner cell mass if this inner cell mass is allowed to continue to develop without harvesting what would ir normally become

-a fetus; the tissues organs and systems of the body

27

if a a trait is not displayed in phenotype**FINISH

recessive

28

immature cells that can divide repeatedly and give rise to more specialized cell types; helps regenerate tissues

stem cells

29

are an organized group of cells that work together to carry out a function

tissues

30

are composed of groups of tissues
often made of multiple cell types
layers of tissues

organs
