Consider this mating between genotypes AaBBccDd and AabbCCDd, where A, B, C and D are loci that assort independently and the uppercase and lower case letter indicate the dominant allele and recessive allele respectively. a. What is the probability that any given offspring of this pair will be heterozygous at all loci?b. What is the probability that an offspring will be homozygous at all four loci?c. What is the probability that an offspring will be phenotypically dominant?

Explanation:

AaBBccDd x AabbCCDDd ---Parents

Aa x Aa = AA (1/4), Aa (1/2) & aa (1/4)

BB x bb = Bb (1)

cc x CC = Cc (1)

Dd x Dd = DD (1/4), Dd (1/2), dd (1/4)

a). The probability that any given offspring of this pair will be heterozygous at all loci = AaBbCcDd = ½ * 1*1*1/2 = ¼

b). The probability that an offspring will be homozygous at all four loci =AABBCCDD = ¼*0*0*1/4 = 0

c). The probability that an offspring will be phenotypically dominant = A_B_C_D_ = ¾ * 1 * 1* ¾ = 9/16

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .

1)

i))the process of preparing food by green plants in the presence of sunlight is called photosynthesis.

ii) leaf is the site for photosynthesis.

iii) it takes place as,
