1. When a strain of fruit flies homozygous for light body color is crossed with a strain of fruit flies homozygous for dark body color, all the offspring have light body color. This illustrates Mendel's principle of (1) segregation (2) domi- nance (3) incomplete dominance (4) indepen- dent assortment

Suppose you carry out a cross with fruit flies where you follow the inheritance of alleles at four different gene loci: one locus controls body color, one locus controls eye color, one locus controls wing length, and one locus controls wing shape. At each locus, there is a dominant allele and a recessive allele. The four loci follow Mendel's principle of independent assortment. A male that is heterozygous for all four loci is crossed with a female that is also heterozygous at all four loci. Complete the sentences that predict the results of this cross using the correct terms.The probability that a male gamete will have all four recessive alleles is .The probability that the F₁ offspring will have two dominant alleles at the gene locus that controls body color is .The probability that the F₁ offspring will be homozygous at the gene locus that controls body color is .The probability that the F₁ offspring will have two dominant alleles at all four gene loci is .The probability that the F₁ offspring will have the dominant phenotype for all four traits is .

Mendel's law of segregation indicates thatgametes are diploid.more gametes carrying the dominant allele are produced than gametes carrying the recessive allele.gametes have one allele copy for each gene.two alleles segregate into each gamete.

Mendel's principle of independent assortment applies to traits whose genes are found on (1) homologous chromosomes (2) sex chromo- somes (3) the same chromosome (4) nonho- mologous chromosomes

Mendel found that due to _____, certain traits do not demonstrate independent assortment.

In fruit flies, the gene for red eyes(R) is dominant over the gene for white eyes(r) and is sex linked. If a true breeding red eyed male, all the offspring are red eyed. However, if a true breeding white eye breeding white eye female is mated with a red eyed male, all the offspring will be white eyed. Explain this apparent contradiction using genetic cross
