      c      c

C   Cc     Cc

c    cc      cc

The genotype of the offsprings would be Cc, Cc, cc, cc i.e heterozygous cleft chin and no cleft chin. The phenotype of the offsprings could be 50% cleft chin and 50% without cleft chin.

there will be 50% chance of the child to have cleft chin.

        A        a

A     Aa       Aa

a      Aa        aa

There will be 25% chance for the offspring to have arched feet. As arched feet is a recessive trait, so for this trait to occur both the alleles of the gene should be recessive i.e aa.

Answer No 4:

    B      b

b   Bb    bb

b    Bb    bb

As blonde is a recessive trait, so both the alleles for this gene should be recessive for this trait to occur. Hence, according to the punnet square, there will be 50% chance for the offspring to be blonde.

Answer No 5:

           F      f

F          FF    Ff

f           Ff     ff

As normal vision is a resessive trait, hence both the alleles of the gene should be recessive for the trait to occur. According to the punnet square, there is 25% chance that the child will have normal vision.

Use a protractor to draw a parallelogram that has two side lengths of 5 inches and 2 inches and two adjacent angles that measure
Irina18 [472]

If the adjacent angles of a parallelogram measure 25° and 155°, the other two angles would measure 25° and 155°

<h3>What is a parallelogram?</h3>

A parallelogram is a quadrilateral (has four sides and four angles) in which both sides are equal and parallel to each other. Opposite angles of a parallelogram have the same measure and the diagonals are equal in length.

If the adjacent angles of a parallelogram measure 25° and 155°, the other two angles would measure 25° and 155° because opposite angles are equal.
