Question

1) when the two genes in a pair are identical the individual is ______ or _______.

2)If Both genes are Dominant (YY) the individual is ______.

3)If both genes are recessive (yy) the indivual is ______.

4) Individuals with a dominant and a recessive gene (Yy) are _________ or __________.

5) when you look at someone the traits you see are there : either genotype or phenotype.

Answer 1

1) when the two genes in a pair are identical the individual is _homozygous dominant_ or _homozygous recessive_.

2)If Both genes are Dominant (YY) the individual is _Homozygous Dominant_.

3)If both genes are recessive (yy) the indivual is _Homozygous recessive_.

4) Individuals with a dominant and a recessive gene (Yy) are _heterozygous_.

5) when you look at someone the traits you see are their phenotype.

Answer 2

Remember that the word part "homo" means "same".
The word part "hetero" means different.

Homozygous is "same - o - zygous", so the letters of the genotype are the same. ... BB or bb.

Heterozygous: the letters of the genotype are different ... Bb or bB.

BB is homozygous dominant.
bb is homozygous recessive.

When you tell what the genes say (like Bb or bb), you're telling the genotype.

When you tell how the organism turns out, you're telling the phenotype.

You can use this information to answer your questions.

Answer 3

YY or yy (Homozygous Dominant or homozygous recessive)

heterozygous or hybrid

phenotype (you cant see someone's genotype though racist people claim that ability!!)
