M5: Monohybrid Crossess and Inherritance

Question 1

What is a Punnett square?

Answer 1

Four possible outcomes for a certain trait in each cell

Question 2

What is a genotype?

Answer 2

shows which alleles - versions of a trait - eg bb, BB, Bb

Question 3

What is a phenotype?

Answer 3

Physical traits are expressed, e.g., brown eyes, blonde hair, etc.

Question 4

What is a heterozygote?

Answer 4

one dominant, one recessive

Question 5

What is a homozygote?

Answer 5

two dominant or two recessive

Question 6

What are Mendel’s laws of inheritance?

Answer 6

1. Law of dominance
2. law of segregation
3. law of independent assortment

Question 7

law of dominance?

Answer 7

states that some alleles are dominant over other alleles for that gene

Question 8

law of segregation?

Answer 8

states that one parent just gives one allele for a gene to each gamete they produce

Question 9

law of independent assortment?

Answer 9

state sthat during gamete formation, different pairs of alleles segregate independently of each other. equal probability of occurring in each gamete

Question 10

what is a pedigree chart?

Answer 10

a diagram that shows occurance and appearence of phenotypes of a particular gene expressed over generations

Question 11

types of inheritance?

Answer 11

autosomal - trait follows mendelian inherritance pattern

autosomal recessive - expressed as recessive, skips a gen most times

autosomal dominant - carries at leats one affected allele, does no skip a gen
