Lets say that the genotypes are:
Male affected:XbY
Male unaffected: XaY
Female affected: XbXb
Female carrier: XaXb
Female unaffected:XaXa
P: XbY x XaXa
F1: XaXb XaXb XaY XaY The middle square is female carrier.
P:XbY x XaXb
F1: XaXb XbXb XaY XbY The left square is affected female.
P:XaY x XbXb
F1: XaXb XaXb XbY XbY The right square is affected male.
Answer:
here is your Answer.
Explanation:
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants .
The correct answer is option B. The scientists were studying if the mud snails can reproduce both sexually and asexually. The characteristics in the study included parameters such as the mating season, number of offspring, effect of environmental stress conditions and lack of mates. Out of all the parameters being studied can affect asexual reproduction in the mud snail but lack or presence of mates is a parameter required to be studied to determine the mode of reproduction i.e. sexual or asexual because need for mates or mate dependent reproduction occurs in case of sexual reproduction.
There are many benefits provided by biodiversity. It can be in our biological resources, ecosystem services and also social benefits. The three social benefits provided by biodiversity would be the following:
1. Research, education and monitoring
2. Recreation & tourism
3. Cultural values
Explanation:
Biodiversity is “the variability among existing animals from all causes including temporal, marine and other aquatic ecosystems, and the environmental complex.
Pollinators, including bees and butterflies, contribute meaningful environmental and economic advantages to agricultural and essential ecosystems, including adding heterogeneity and productivity to food crops. As many as one-third of the world's food production relies directly or indirectly on insect pollination.
