Solution

QUESTION 16

What is the probability of producing a child that will phenotypically resemble either one of the two patents in the following four crosses? How many phenotypically different kinds of progeny could potentially reach each of the four crosses?

A-d is pictured please explain how you crosssed each one (genetics)

Number of gametes=2^n

N=number of heterozygous locus

CROSS A

A )Aa Bb Cc Dd          x aabbccdd

Aa Bb Cc Dd         

abcd

2^n =2^4=

One type gamete

Hence there possibility of 16 types of offsprings

16 TYPES OF GAMETES

CROSS B

B )      aa bb cc dd          x AABBCCDD

AA BB CC DD         

abcd

One type gamete

One type gamete

Hence there possibility of ONE types of offspring

CROSS C

C )      Aa Bb Cc Dd          x Aa Bb Cc Dd         

Aa Bb Cc Dd         

Aa Bb Cc Dd         

2^4 =16

Types of gamete

16   type gamete

Hence there possibility of 256 types of offspring

CROSS d

d )      aa bb cc dd          x aabbccdd

abcd

abcd

One type gamete

One type gamete

Hence there possibility of ONE types of offspring

Aa Bb Cc Dd	abcd
2^n =2^4=	One type gamete	Hence there possibility of 16 types of offsprings
